Answer:
SAS
Step-by-step explanation:
GIVEN: BD=AC
angle BAD= angle ADC because they are both 90 degrees.
AB=DC because both are right triangles
Answer:
48

I think it would be a and f :)
Answer:
∠ 1 = 109° , ∠ 2 = 29° , ∠ 3 = 71°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 35° + 36° = 180°
∠ 1 + 71° = 180° ( subtract 71° from both sides )
∠ 1 = 109°
-------------------
∠ RVU and ∠ 1 are adjacent angles on a straight line and sum to 180° , then
∠ RVU + ∠ 1 = 180°
∠ RVU + 109° = 180° ( subtract 109° from both sides )
∠ RVU = 71°
In Δ RVU
∠ 2 + 80° + 71° = 180° ( sum of angles in triangle )
∠ 2 + 151° = 180° ( subtract 151° from both sides )
∠ 2 = 29°
-------------------------
∠ 3 and ∠ RVU are vertically opposite angles and are congruent , then
∠ 3 = 71°

Answer:
- GX = 122°
- XU = 148°
- UG = 90°
Step-by-step explanation:
Each arc has the same measure as its central angle. The sum of all of them is 360°.
angle UOG is marked as a 90° angle, so arc UG is 90°.
angle GOX is marked as 122°, so arc GX is 122°.
angle XOU fills out the rest of 360°, so its measure is 360° -90° -122° = 148°. That means are XU is 148°.
The arc measures are ...
- GX = 122°
- XU = 148°
- UG = 90°
