Answer:
Step-by-step explanation:
14) 2x - 10 = 80 {alternate interior angles are equal}
2x = 80 + 10
2x = 90
x = 90/2
x = 45°
15) 3x + 120 = 180 { co interior angles are supplementary}
3x = 180 - 120
3x = 60
x = 60/3
x = 20°
16) 3x + 15 = 135 {corresponding angles are equal}
3x = 165 - 15
3x = 150
x = 150/3
x = 50°
Answer:
The answer for y=2x−2 is x=y/2+1
Step-by-step explanation:
To find area you need to multiply
length x width
Since 49 can be square rooted it equals seven
L x W = Area
Area = 7 x 7
Area = 49
Meaning since it’s a square the perimeter is
7 by 7 by 7 by 7 in other words 7 + 7 + 7 + 7 OR 7 x 4(equal sides)
