I'm assuming ya want us to simplify 
reemember some exponential rules
so
Answer:
43°
Step-by-step explanation:
p + 7° + 3p+ 1° = 180° ( Being linear pair)
4p + 8° = 180°
4p = 180° - 8 °
4p = 172°
p = 172° / 4
p = 43°

Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72
We will get shaded area when we subtract rectangle area from semicircle area.
Rectangle area is Ar=a*b=16*6= 96 cm∧2
Semicircle area is Asc= (r∧2 pi)/2
First we must find radius.
We know that the center of the semicircle ( or circle) is in the middle of the longer side of the rectangle.
Now we can find radius with Pythagorean theorem
r= √8∧2+6∧2= √64+36 =√100= 10cm => r= 10 cm
Asc=(10∧2 * pi)/2 = 50 pi cm∧2
Shaded area is Asc - Ar = 50pi - 96 = 2 (25pi-48) cm∧2
Good luck!!!
