The unknown angle measures are 45°,110°,115°,115°.
What is angle measurement?
An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry. A protractor is used to measure angles in degrees (°).
The angle for the first triangle has the angles of 70°,45° will be 65°. The angle is the complementary angle with the 65°. Hence the angle of the top on the right side will be 115°.
For the equal and opposite vertices angles are equal. Hence for the second triangle, the angle opposite the 45° is 45°.
On the left of 65° is 115° . Because the sum of the complementary angle is 180°
Below 110° is 110° . Because of the equal and opposite vertices.
Hence the unknown angle measures are 45°,110°,115°,115°.
