5)
x = 132 - 42
x = 90
Answer
90 degrees, right angle
6)
180 - 126 = 54
The other two are congruent so 54/2 = 27
Answer
27
7)
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
6x = 38 + 82
6x = 120
x = 20
Answer
20
8)
Sum of interior in a triangle = 180 degrees
So
2x - 3 + 23 + 128 = 180
2x + 148 = 180
2x = 32
x = 16
Answer
16
Answer:
A = X+10
Step-by-step explanation:
with the given information, this is the equation you're looking for
87/6-66/6
=21/6
=3 3/6
=3 1/2
=3.5
so 4 to the fourth power is 16 and 16 to the fourth power is 65,536
