Answer:
x=1, 5
Step-by-step explanation:
0 = 4(x - 3)^2 - 16
Add 16 to each side
0+16 = 4(x - 3)^2 - 16+16
16 = 4(x - 3)^2
Divide each side by 4
16/4 = (x-3)^2
4 = (x-3)^2
Take the square root of each side
±sqrt(4) = sqrt( (x-3)^2)
±2 = (x-3)
Add 3 to each side
3±2 = x-3+3
3+2 =x so x=5
3-2 =x so x=1
Answer:
the value of x is 50 and the measure of c is 70°
Step-by-step explanation:
x+20+2x-30+40=180 (sum of inside the triangle is 180°)
3x+30=180
3x=180-30
x=150/3
x=50
