Answer:
B
Step-by-step explanation:
Y=3x. The slope is 3 6-(-6)/2-(-2) and the y intercept is 0.
All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
216 divided by 3 is 72 so making the answer
1/72
6²+8²=c²
36+64=c²
c²=100
c=10
Answer:
C
Step-by-step explanation:
x^2 + (x+3)^2 = 117
x^2 + x^2+6x+9 =117
2x^2 + 6x - 108 = 0
(2x-12)(x+9)=0
x=-9,6
x cannot be negative therefore, x = 6
