Answer:
1) 145°
2) 20°
3) x = 7 ; measurement of the missing angle = 24
Step-by-step explanation:
1) supplement = 180°, 180 - 35 = 145
2) complment = 90° , 90 - 70 = 20
3) the figure is a right angle so the measurement is 90°
66 + (4x-4) = 90
62 + 4x = 90
4x = 28
x = 7
4(7) - 4
28 - 4
= 24
Answer: -1.3125
Step-by-step explanation:
(-1/4 - 1/2) = -0.75
-0.75/
= -1.3125
1/(-9)^2 = 1/81 just that

Answer:
C. 5/4x-2=3/4x-4
Step-by-step explanation:
Add 2 to both sides
5/4x-2+2=3/2x-4+2
Simplify
5/4x=3/2x-2
Subtract 3/2x from both sides
5/4x-3/2x=3/2x-2-3/2x
Simplify
-1/4x=-2
Multiply both sides by -1
(-1/4x)(-4)=(-2)(-4)
Simplify
x=8
