Question

find the measure of an angle A in each figure given reason in each case

Answer 1

i question 130 degree because linear pair is 180 degree so answer is 130 degree


ii question
43 degree because vertically opposite angle


iii question
55 degree because sum of complete angle is 360 degree

iv question
27 degree because sum of complementary angle is 90degree



finally i = 130
ii =43
iii =55
iv= 27



mark me as brainliest

Answer 2

ii)
angle a=43°. {Vertically opposite Angle}

iii)
angle a =360-(209+96)=>55°. {angle around a point is 360°}

iv)
angle a=90-63=>63°. {right angle }

i)
angle a=90-50=>40°. {supplementary Angle}
