Question

If angle a and angle d are supplementary angles and m angle=(x-20)then what would be m angle a

Answer 1

Answer:

your answer is given below.....

Step-by-step explanation:

let let the measurement of angle a=x

measurement of second Angle b=x-20

then, x + x - 20 =180 degree

2x=200°

x=200/2

x=100

===.============.=========

hence, value of angle a = 100 degree

value of Angle b= (x-20)=(100-20)=80°
