Angle 3 = 180° - 70°
Angle 3 = 110°
Angle 2 = 180° - (110° + 36°)
Angle 2 = 180° - 146°
Angle 2 = 34°
Angle 4 = 180° - 70°
Angle 4 = 110°
Angle 5 = 180° - (110° + 62°)
Angle 5 = 180° - 172°
Angle 5 = 8°
I hope this helps.
Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
Answer:

Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
f(x)=16x-30 and g(x)=14x-6
(f-g)(x)=0
f(x)=16x-30 -(14x-6)
Distribute
= 16x -30 -14x +6
Combine like terms
= 16x-14x -30+6
2x-24
Set this equal to zero
2x-24 =0
Add 24 to each side
2x-24 +24=0+24
2x=24
Divide by 2
2x/2 =24/2
x = 12
