Step-by-step explanation:
Given:

To make
the subject of the formula means that we want to make
to stand alone , the first thing to do is to multiply through by 1/4a , that is

take the square of both sides:

The measure of the intercepted arc (a) is twice the measure of the inscribed angle intercepting it (b or 25°). The measures of the inscribed angles are all the same: b = 25°.
The appropriate choice is D. 25
Answer:
The Answer is A. 2/5
Step-by-step explanation:
The way i Divide fractions is by if you take the second fraction and swap the numbers around, you can do 7/24 TIMES 48/35. then you multiply the numbers NOT in a crossway like 7 times 35 butin a straight way so its 7 times 48. Doing so will get you 336/840. I simplified this answer by 6 and got 56/140 then i simplified it again by 4 to get 14/35 and once more i simplified it by 7 to get 2/5.
