find the missing x of the right angled triangle of ABC.Hypotenuse=x + 2 , altitude = 5, base= x – 3 and angle B is 90 degree.​

Answer»

Answer:

x=3

Step-by-step explanation:

AC² = BC² + AB²

(x+2)² = (x-3)² + 5²

x² + 4X +4 = x² -6x +9 + 25

x² - x² = -6x-4x+34-4

0 = -10X + 30

10x = 30

x = 30/10 = 3

Please help me solve this.... pleaseeeeeee​

Answer»

Given that,

cos x = - 4/5

COSINE is NEGATIVE in second and third quadrant but with accordance to given constraints, x WOULD lie in second quadrant where SINE is positive.

We know that,

sin²x + cos²x = 1

\longrightarrow sin²x + 16/25 = 1

\longrightarrow sin²x = 9/25

\longrightarrow sin x = 3/5 (Second Quadrant)

Thus,

sin2x

\longrightarrow 2 × 3/5 × -4/5

\longrightarrow -2 × 12/25

\longrightarrow -24/25

Express y in terms of x linear equation -2x+7-y=0 and check whether the point (-3,-2) lies as the line.

Answer»

Step-by-step explanation:

y=- -2x+7

Now put the value of (-3, -2) in the equation.

LHS = -2(-3)+7-(-2)

= 6+7+2

= 15

≠ RHS

so the point (-3, -2) does not lie on the GIVEN LINE.

Answer»

ANSWER:

(a) ৩০ বছর

Step-by-step explanation:

ধরি  তিন বছর আগে রহিম ও করিমের বয়স ছিল x এবং y .

তাহলে (x + y)/2 = 18

=> x + y = 36 ......... (i)

ধরি আলমের বয়স z

তাহলে (x + y + z)/3 = 22

=> x +  y + z = 66 ......... (ii)

(ii) থেকে (i) বিয়োগ করলে আমরা পাই

z = 30

তাহলে আলমের বয়স হল ৩০ বছর.

A motorboat goes downstream in a river and covers a distance of 64km in 2 hours, while coming back to the starting point, the boat takes hours. The speed of the motorboat in still water and the speed of the stream respectively are :A. 20km/h and 8km/h B. 28km/h and 4km/hC. 30km/h and 2km/h D. 32km/h and 3km/h ​​

Answer»

Answer:

SPEED of boat = 30 km/h;

speed of stream = 2km/h;

Step-by-step EXPLANATION:

let stream speed be y and boat stream be X;

in general: S=D/T;

t=d/s(total);

s(total) (while  downstream)=x+y;

t(downstream) = d/(speed(downstream));

s(total) (while UPSTREAM)=x-y;

t(upstream) = d/(speed(upstream));

2= 64/(x+y);

2x +2y =64;........(1);

16/7=64/x-y;

16x-16y= 448;..............(2);

by multiplying (1 )*8

16x+16y=512;

16x-16y=448;

32x=960;

x=30;

2x+2y=64;(1)

60+2y=64;

2y=4;

y=2;

therefore, speed of boat = 30 km/h;

speed of stream = 2km/h;

hope you find this HELPFUL.
