Answer:
angle C =160 degree
Step-by-step explanation:
since the given triangle is an isosceles triangle their base angles must be equal. So,
x - 10 =x/2
2(x - 10) =x
2x - 20 = x
2x - x = 20
x = 20
for angle B
x - 10
20 - 10
10 degree
for angle A
x/2
20/2
10
For angle c
angle A + angle B + angle C =180 degree (sum of interior angle of a triangle)
10 + 10 + angle C =180
20 + angle C =180
angle C =180 - 20
angle C =160 degree
Answer:
y=1/4x+3
Step-by-step explanation:
To find the inverse, switch x and y or f(x)
f(x)=4x-12
y=4x-12
x=4y-12
Add 12 to both sides
x+12=4y-12+12
x+12=4y
Divide both sides by 4
x+12/4=y
1/4x+12/4=y
1/4x+3=y
y=1/4x+3
