Answer:
15°
Step-by-step explanation:
The line in the middle of the triangle divides it into two triangles. These two triangles are equal. You can see this because the given angle (90°) is equal for both sides, and the bottom sides (23) are also equal to each other.
Since the triangles are equal, this means that the given angle of 75° also applies to the other side. The total degrees a triangle can have is 180°. Use the given angles to solve for the unknown angle.
75° + 90° + x = 180°
165° + x = 180°
x = 15°
The angle measure will be 15°.
Answer:
2970
Step-by-step explanation:
2700+ 270
270 because that is 10% of 2700
2700 because that is 75 x 36
Subtract 1 to 13. so you got 12. divide 4 so you can get the S by it self.S=3.
