Answer is in the pic above. Theorems used:
Exterior angle theorem
Inscribed angle theorem.
I think the answer is 14 6/3
EXPLANATION
Applying the Angles in Circles Theorem we can assevere that the measure of the unknown angles is given by the difference between 360 (By the Sum of Interior Angles of a Quadrilateral Theorem) and the angle 114 with both right angles.
? = 360 -114 - 90 - 90
? = 66 degrees
The answer is 66 degrees
Answer:
9
Step-by-step explanation:
1. You would make these to equations equal to each other because there are parellel(they have the same angel)
2. EQUAL these 2 equations together to find r.
3. SOLVING for r
7r - 5 = 6r + 4
r = 9
Step-by-step explanation:
A ; 2 × 12 = 3×4
B; 2 × 12 = 3×6
C ; 2 × 18 = 3×18
D; 2 × 36 = 3× 12
