area of triangle = 1/2* base* height=(1/2*14*8)cm sq=(1/2*112)cm sq=56 cm sq

a+50°+50°=180a=80°and we know that angle subtended by an arc at centre is double angle subtended by it at any point on the remaining part of the circlesince a/2=b=80/2=40°

a=80as, 180-(50+50)180-100=80b=40

a=80180-(50+50)180-100=80b=40

a = 50 - 180a = 130

b = 130 - 180 b = 50

a=80 ,b=40 is the correct answer

40° is 100% guaranteed correct answer

a=80° and b=40° is correct answer

a=80 b=40 is the correct and best answer

50+50+a=180। so a=80। and b=40

So easy...a=80°and b=40°.........▪︎▪︎(half of angle a)

a=80° and b=40° is the right answer

a=80°180° - (50+50) 180-100=80b=40° answer

a=80180- (50+50)180- 100=80b=40

angle a =80angle b=40

50+50+x=180(because triangle three side of is add 180)

a=80as,180-(50+50)b=40

given an angle 50 ° equal front angle because both sides are equaltherefore a=80°b=1/2 of ab=40

70° is the correct answer

a= 80 and b= 40..........

A=80 B=40is the best answer

a=80as, 180-(50+50)180-100=80b=40.

a=80'andb=80'(acchuli AK hi vartya khand ke angle =hote hai)

a=80b=40.................

a=80b=40 uis the correct answer.

a= 80,b=40 is answer

50+50+a = 180=100+a=180a=180-100 a= 80 ans

50 + 50 + a = 180 (angle sum prop. of traingle) 100 + a = 180a = 180 - 100a = 80

b = 80/2 = 40 ( angle subtended by an arc at Centre is double angle subtended by it at any remaining part of the circle)

a=80as,180-(50+50)180-100=80b=40

त्रिभुज के तीनों कोनो मान=180तो कोन A+B+C=180 A+50+50=180 A+100=180 A=180-100 A=80

A-80 B-40 is right answer

a=80°and b=40° that is answer that question

a=80° and b=40 that is answer to your question

a = 80° and b = 40°{because 50+50+a=180°= a = 80°}

answer for this question is a=80,b=40

a ki value 80 b ki value 90

In (1) I am not able to understand how total no. of event 36.please explain me.please

first term=43 arithmetic terms are insertedthen 5th term=5a+(5-1)d=5;4+4d=5;d=1/4then the three terms between 4 and 5 are 17/4,18/4,19/4

100(CP)==20%(up)==>120(MP)==10%(disc.)==>108.% gain = 8%.

as right triangle follows Pythagoras theorem so let the base be 15 and perpendicular be x 15² + x² = 39² x² = 1521 - 225 x² = 1296 x = 36so other side is 36

Perimeter of semicircular wire = pi × r

Perimeter of semicircular wire = 22/7×7 cm = 22

Length of the diameter = 2r = 14

Total length = 22 cm + 14 cm = 36 cm

7/16 - 7/48

= 7*3/16*3 - 7/48

= 21/48 - 7/48

= 14/48

÷ by 2,

= 7/24

Like my answer if you find it useful!

i) total prime no. in a die = 2,3,5 so, p ( getting a prime ) = 3/6 = 1/2

ii) no. not greater than 5 = 1,2,3,4,5

so, p( getting a number not greater than 5) = 5/6

Proof:Let, tan−1x = θ

Therefore, x = tan θ

x = cot (π2- θ), [Since, cot (π2- θ) = tan θ]

⇒ cot−1x =π2- θ

⇒ cot−1x=π2- tan−1x, [Since, θ = tan−1x]

⇒ cot−1x + tan−1x =π2⇒ tan−1x + cot−1x =π2

Therefore, tan−1x + cot−1x =π2.Proved.

68 is the correct answer of the given question is

68 is right answer for your question

perimeter = 68 is correct answer

perimeter= 68 correct answer

To show :7 × 11 × 13 + 7 is composite numberProof:

7×11×13+7=7(11×13+1)=7(143+1)=7×144=7 × 2×2×2×2×3×3=7 × 2⁴ × 3²

It is the product of prime factors 7, 2 and 3.

Hence, it is a composite numberLike if you find it useful

wow the answer is. 0.14

Perimeter of one face of the cube = 40 cmTherefore, one edge = 40/4Length of one edge = 10 cmTotal number of edges of a cube = 12Sum of the length of its edges = 12*10= 120 cm

My next doubt please solve

Given:length (l) =5 cm, breadth (b) =3.5 cmTo find : the perimeter

Solution : perimeter of a rectangle = 2( l× b)=2(5×3.5)=2×17.5=35"perimeter = 35 cm

An odd number is any number not divisible bytwo. A composite number is a number with more than one prime factor. So an odd composite hastwoor more prime factors, none of which aretwo.

1 × 3 × 5 × 7 + 7

7 ( 3 × 5 + 1)

So, given has two factors other than the number itself and 1.

so it is a composite number.

s1= 36 cms2 = 20 cms3 = 84-36-20= 28 cmusing formula,perimeter = s1+s2+s3

semiperimeter, s = perimeter /2 = 84/2=42 cm

area = square root of (s*(s-s1)*(s-s2)*(s-s3))

subatituting values,

area = 278.596 cm2
