A is the intercepted arc of the angle that measures 45 degrees. The rule here is that arc measures twice what the angle measures. If the angle measures 45 degrees, then the arc measures 45 * 2 which is 90 degrees. There has to be another choice there that is cut off. These are inscribed angles, and those are the rules for inscribed angles.
Answer: 39
Step-by-step explanation:
SInce the problem asks for the expression when a=2 and d=5, you olug in the values of a and d and solve.
(5)²+3(2)+6+(2) [exponent]
25+3(2)+6+2 [multiply]
25+6+6+2 [add]
39
After plugging in a=2 and d=5, we got 39 as our answer.
The solution and answer are well written in the Pic above.
