Answer:
b=85º
a=20º
Step-by-step explanation:
Angle B is supplementary with the 45º and the 50º angle, therefore the sum of the three angles must be 180
45+b+50=180
95+b=180
b=85º
Angle A, Angle B, and the 75º angle must also add up to 180
85+75+a=180
160+a=180
a=20º
The answer would be 3. 3 is the largest factor that both numbers have in common.
To simplify the equation, we have y = 
<h3>How to simply the expression</h3>
Given the expression
y-8 = 3/4x [x-(-6)]
First, expand the bracket
= 
Make 'y' the subject of formula
y = 
Thus, to simplify the equation, we have y =
