Answer:
Step-by-step explanation:
Given
Roots = -2 and 5
Required
Write the equation
We have that:
x = -2 and x = 5
Simplify further
x + 2 = 0 or x - 5 = 0
Multiply the results of the above
Open brackets
The angle that has a little square in the corner, is 90 degrees. so you can add 90 and 72 which is 162 and take 180-162 because the line that is on top of them is a straight line. so z= 18 degrees. take 180-72 because the line left to 72 is also straight so x=108.
we know z already equals 18 so add 90+18= 108. subtract 180-108 =72
z=18
x=108
y=72
Answer:
b=76
