You could take it from either of the non-right angles.
To one angle, which side is opposite and which is adjacent is different than to the other angle. This is also why sin(x) = cos(90-x) and cos(x) = sin(90-x).

based on the census state A has 11 fewer electoral votes for president then state b. If the total number of electoral votes for

matrenka [14]

A + b = 87
a = b - 11

b - 11 + b = 87
2b - 11 = 87
2b = 87 + 11
2b = 98
b = 98/2
b = 49 <===

a = b - 11
a = 49 - 11
a = 38 <===

A triangle has one side that measures 12, another side that measures x, and a third side that measures 4 less than x. The perime

Setler79 [48]

Perimeter = sum of all 3 sides in a triangle
so
x + x - 4 + 12= 26
answer
B. <span>x + x - 4 + 12 = 26</span>
