Question

in a parallelogram abcd if angle a=3x + 15 and angle d=2x-5then find the value of x then find measure of angle a and angle d

Answer 1

Heyaa....
_____________________________

In a parallelogram we know that sum of adjacent angles = 180

So 3x + 15 + 2x - 5 = 180
5x + 10 = 180
5x = 180-10
x = 170/5
x = 34

So angle A = 3x + 15 = 3×34 + 15 = 117
Angle D = 2x - 5 = 2×34 - 5 = 63
