Answer:
Part 1)
Part 2)
Step-by-step explanation:
Part 1) what is the measure of angle AFE
we know that
The measure of the interior angle is the semisum of the arches that comprise it and its opposite.
<u>Note:</u> In this problem the correct measure of arc EA is 40 degrees (see the picture)
so
substitute the given values
Part 2) what is the measure of angle EFB?
we know that
---> by supplementary angles (form a linear pair)
so
substitute the given value
Answer:
no
Step-by-step explanation:
the two smaller numbers added together need to be greater than or equal to the larger number
5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
You need to add the two quadratics together...
x^2+11x-6+6x^2-3x+9
7x^2+8x+3
Answer:
4squared is 16 so 16×16=256
hope it help
