Answer:
A:48 B:45
Step-by-step explanation:
The measurements of an angle X is 80
B2-7b+12=0
(b-3)(b-4)=0
b= 3 or 4
Answer:
x = 6
y = 24
z = there is no z?
Step-by-step explanation:
All angles of a polygon add up to 360 degrees
The 2 parellel lines on top and bottom mean that there are 2 right angles on the left side
3y + 18 = 90
3y = 72
y = 24
15x + 30 + 10x = 180
25x = 150
x = 6
