30 + 4x + 2 + 180 - (8 + 6x) = 180;The sum of all angles in a triangle is 180
32 + 4x - 8 - 6x = 0
2x = 24
x = 12
Bolded part, explanation: On a straight line, the sum of all angles is 180 degrees. We have the value of outside the triangle, the exterior angle, which, when is added with interior angle, gives 180 degrees. So we substract 8 + 6x from 180, that's the third angle in a triangle.

Answer:
x=21
Step-by-step explanation:
61+34 = 95
360( a circle) - 95 = 265
265 +7 +22 = 294
9x+5x=14x
294=14x (divide both by 14 to get x)
X=21
Answer:
x = 1 and y = -3
Step-by-step explanation:
Subtract eqn 1 from eqn 2
11y = - 33
y = -3
Substituting y into eqn 2...
10x - 2(-3) = 16
10x +6 = 16
10x = 10
x = 1
Answer:
18
Step-by-step explanation:
perimeter of the base = 4+4+5+5=18
the first box will make up the base of the prism
and perimeter is the sum of the sides of the shape
