Question

this is the last photo plls anyone help me.
I really mark you brainleast and follow you and thanks and rate your answer!! ​

Answer 1

Answer:

ans no.8)

x=55°(Vertically opposite angle)

y=180°-55°(Linear pair)

y=125°

z=125°(Vertically opposite angle)

Answer 2

Step-by-step explanation:

4)

let, x and y are two complementary angles

and sum of complementary angles is 90

therefore,

x+y =90

but, by given condition,

x=5y

therefore

y + 5y =90

6y=90

y=90/6

y=15 and x=90-15=75

therefore,

measure of one angle is 15 and another is 75
