the side of BC of TRIANGLE ABC is produced to D If the bisector of angle A meets BC in E. prove that angle abc + angle acd = 2 angle AEC

Solution:

the bisector of angle A meets BC in E

=> ∠BAE = ∠CAE = x

Let SAY ∠ABC = ∠ABE = α  ( as E is on BC)

∠AEC = ∠ABE + ∠BAE

=> ∠AEC = α + x

∠ACD = ∠AEC + ∠CAE

=> ∠ACD = α + x + x

∠ABC +  ∠ACD  = α + α + x + x

=> ∠ABC +  ∠ACD = 2 ( α + x)

=> ∠ABC +  ∠ACD = 2∠AEC

ANSWER:

are you SURE about the QUESTION U r TRYING to ask

ANSWER:

Step-by-step explanation:

Tan THETA = -4/3

tan theta= perpendicular/bas

- 4/3 = p/b

And,

》》》 h = ROOT under -4 ^2 + 3^2

》》》 h = root 16 + 9 = root 25 = 5

so,

sin theta = P/B = -4/5

Cos theta = B/H = 3/5

》》 Sin theta + Cos theta = - 4 / 5 + 3/5 = -1/5

Answer:

Assuming you have either ENDPOINT of the diameter of a circle, you can USE the midpoint formula to find the point midway between the two points. According to the DEFINITION of a diameter, this will be the circle's center point. If you have the points (x1,Y1) and (x2,y2) , the midpoint formula is (x1+x22,y1+y22) .

Step-by-step EXPLANATION:triangle ABC and triangle PQR are similar. SO,we can say AB IS LARGER THEN PQ. viz ∆ABC is bigger.

(PLS MARK ME AS BRAINLEST)

ANSWER:

Step-by-step explanation:

Let,

The triangle having 9 units as base and 5 units as height is ∆ ABC

And,the triangle having 10 units as base and 6 units as height is ∆ PQR

___________________

Now,

Area of ∆ ABC = (base × height)/2

Area of ∆ ABC =(8×5)/2

Area of ∆ ABC = 40/2 = 20 unit²

-----------------------

Area of ∆ PQR = (10×6)/2

Area of ∆ PQR = 10×3=30 unit²

--------------------

Ratio = 22.5 : 30

what do you MEAN with this QUESTION

ANSWER:

3

Step-by-step explanation:

1st of all 2/2= 1

=> 2+1= 3

So, 3 is the answer

ANSWER:

-4=2(p-2)

-4=2p-4

-4+4=2p

0=2p

1/2=p

TAN 30 = 1 / and tan 60 = '

now substituting in the given EQ, we get

= 1+/1-

rationalising , we get

=4+2/2

taking 2 common in the numerator and cancel in the denominator to get

1+

thats the final answer dude

hope u get it pls mark brainliest !!!!  

ANSWER:

Step-by-step explanation:

Answer:

Step-by-step EXPLANATION:

No. Of ZEROES of a POLYNOMIAL is equal to the degree of the polynomial so it can not be LESS than its degree so statement is wrong.

Answer:

p(x) = (x-p) + 729

As p = 9 ,

(x-9) + 729

x + 720

As the highest degree is 1 , the degree of the GIVEN polynomial is 1 and is CALLED linear polynomial.

Answer:

hey mate your answer my dear friend and please mark it brainlist i hope its help you

Step-by-step explanation:

Both BiPC and MPC are GREAT. Depending on your level of interest and future plans, you can take either. If you’re unable to decide, you can opt for MBiPC.

MPC:

Pros:

IIT, NIT, BITS, NIE and such prestigious colleges.

Good salary.

Innovation and creativity involved.

You are open to many, many OPTIONS in the end. Not only engineering.

Cons:

Huge competition.

Huge pressure to perform.

Marks matter a lot. A LOT. (JEE aspirants will understand this.)

BiPC:

Pros:

You can save lives.

You can save generations.

You can improve the quality of life.

You can have an independent career, rather than working for a firm.

Cons:

Needs A LOT OF MUGGING UP. Photographic memory, if I may add.

YOU CANNOT AFFORD TO BE SLOPPY AND LAZY.

Cutting up frogs and cockroaches. (Not everyone’s cup of tea.)

Huge competition.

Huge pressure to perform.

As I am not from the biology group, I may be biased in favor of MPC. But strangely, I chose MPC in SPITE of the fact that I hated math and scored brilliantly in biology (ICSE). No peer/parent pressure.

Biology is beautiful. Math is mind-blowing. Physics is gorgeous. Chemistry is attractive. :)

Also, from the career POINT of view, generally MPC is preferred by people wanting to go for engineering and architecture. BiPC is preferred by people wanting to pursue medical (dental, AYURVEDA, homoeopathy, pathology, optometry, physiotherapy, psychiatry, gynecology, veterinary science and so on… whew!) and B. Sc.

TWO Angles are COMPLEMENTARY when they ADD up to 90 degrees

so

3x-15+x-5=90

4x-20=90

4x=90+20

4x=110

x= 110/4

x=27.5

3x-15=3*27.5-15=67.5

x-5=27.5-5=22.5

verification

3x-15+x-5=90

67.5+22.5=90

90=90
