Question

in triangle ABC measurement of C =40° measure of angle A and B are in the ratio 3:4 find the value of angle A and B​

Answer 1

Step-by-step explanation:

first in anglec make angle40° and then in solving equation write a+b+c+ =180 then 3x+4x+40°=180°then solving this equation u will get the value of x and then like 3x = 3 whatever the value of 3 will come write and then multiply with it so the answer will come

Answer 2

Anwer= ∆A = 60°, ∆B =80°.

step by step explanation:

let the ∆A + ∆B = x°

so, ∆ A + ∆B + ∆C = 180°

3x°+ 4x° + 40° = 180°

7x° + 40° = 180°

7x°= 180° - 40° = 140°

x°= 140°/7

x° = 20°

∆A = 3

20°× 3 = 60°

∆B = 4

20° × 4 = 80°

I hope you get your answer so, please liked the answer rate tha anwer and comment kro kaisa laga answer.
