Answer:
D
Step-by-step explanation:
The measure of the inscribed angle RST is half the measure of its intercepted arc, that is
∠ RST = 0.5 × 94° = 47° → D
Step-by-step explanation:
1. a²=25²-15²
a²=(25-15)(25+15)
a²=10×40
a=20
2.b²=10²-6²
b²=(10-6) ×(10+6)
b²=4×16
b=8
Hi so let's try to simplify 1/4... it's already simplified so if you were to try to simplify 2/8 you would divide 2 by 2 and 8 by 2 to get 1/4. But 1/4 isn't = to 1/2. So let's simplify 2/4, first, you would divide 2 by 2 and 4 by 2 to get 1/2. C is the answer!=D I hope this helps.
