Step-by-step explanation:
m∠abc = m∠ebf = 58°
reason: vertical angles
m∠cbf = 180-m∠ebf = 180-58 = 122°
reason: Supplementary angles
m∠dbe = 90-m∠ebf = 90-58 = 32°
reason: complementary angles
Answer:
I believe it's Division property
Step-by-step explanation:
Since 8m = -16
You divide both sides by 8. So -16 divided by 8 will equal to -2. m=-2

Answer:
t = 17.5 f = 12
Step-by-step explanation:
If <em>MNOP </em>is a square, you know that each angle is going to be 90°. To solve, let's first set each equation equal to 90°:
and
Then solve both equations:
and

Answer:
3
Step-by-step explanation:
From a given vertex, two of the vertices are adjacent, so a "diagonal" to those will not form a triangle. The number of diagonals that can be drawn is 3 fewer than the number of sides. The number of triangles is 1 more than the number of diagonals.
For a 5-sided figure, 2 diagonals can be drawn from a common vertex.
3 triangles will be formed.
