Answer:if your still doing this comment and I will try helping
Step-by-step explanation:
The radius of the Outer circle (with r₂) is 6 and the radius of the inner circle (with r₁) is 2. When objects are similar, they have a proportional relationship. If we take the outer circle and squeeze by one third, we get a radius of 6 x 1/3 = 2. On the other hand, if we start with the inner circle and stretch it by 3, we get a radius of 2 x 3 = 6.
Thus, to make r₂ similar, we use a scale factor of 1/3. The third choice is best.
Those are alternate interior so congruent angles,
2x + 15 = 3x
15 = x
Choice A
Answer:
D-70
Step-by-step explanation:
It is a combination C(8,4)
Your answer is B. You multiply 5 by the exponents and 4^0 is just 1, so 4^45•1=4^45. Hope this helped!
