Write down the value of angle y

y= 71   Reason: alternate angle to 71 degrees

z = 44

Step-by-step explanation:

You already solve for x.

y = 71 because it is alternate to 71 degrees you see up there.

For z:

all angles inside a triangle sum upto 180

z=180-(71+65) = 44

Option B

Explanation:

the given function f(x)= 10x when stretch vertically with the factor 1.25 will give g(x) = 1.25.10x

option A and C are totally irrelevant

Option D is incorrect because two numbers 10x and 1.25 when added will not give 101.25x instead it will give 10x +1.25

and we will multiply them not add them.

Note: If a function is compressed then we divide the function by the given factor.
