Answer:
1-Angle 1 and angle 8, angle 2 and angle 7.
2-Angle 3 and angle 6, angle 4 and angle 5.
3-Angle 1 and angle 5, angle 2 and angle 6.
4-Angle 2 and angle 3, angle 5 and angle 8.
Step-by-step explanation:
We are given that in diagram , transversal t cuts across the parallel lines a and b.
We have to match pair of angles with the relationship that show they are congruent.
Alternate interior angles:
Angle 3 and angle 6, angle 4 and angle 5.
Alternate exterior angles:
Angle 1 and angle 8, angle 2 and angle 7.
Corresponding angles:
Angle 1 and angle 5, angle 2 and angle 6.
Vertical angles:
Angle 2 and angle 3, angle 5 and angle 8.
The area of the sector is 86.81π mm²
<u>Explanation:</u>
Given:
Radius of the sector, 25mm
Angle, α = 50°
Area of the sector, A = ?
We know:
Area of the sector =
On substituting the value, we get:
Therefore, the area of the sector is 86.81π mm²
So 1.35 feet pieces of wood
needs 4 pieces
you can solve this by writing the numerical expression
1.35 * 4
5.4
Hope this helps
Answer:
im pretty sure all you have to do is switch the signs (if its negative it will become positive) but only for the points on the x axis so basically (-12,13) would become (12,13)
