Yes the base of a triangle greatly affects the area of the triangle. Half of the base times the height of a triangle equals its area, so therefore the base greatly affects it.<span />
You can use the measure of 112 on the similar shape to find b, as they are same side exterior angles. From there, you can find both a and c, because a/b and b/c are supplementary angles.
a = 68 degrees
c = 68 degrees
let the consecutive multiples be 7(n-1) , 7n and 7(n+1)
so 7(n-1)+7n+7(n+1)=777
or 3n=111,
n=37
252,259,266
I think 90 degrees but not 100 percent sure
Answer:
B
Step-by-step explanation:
2x-5y=13.........(1) × 3
-3x+2y=13.......(2) × 2
6x - 15y = 39
-6x + 4y = 26
Adding
6x - 6x - 15y + 4y = 13 + 13
