we know that
The measurement of the exterior angle is the semi-difference of the arcs which comprises
In this problem
∠FGH is the exterior angle
∠FGH=
∠FGH=
-----> equation A
--------> equation B
Substitute equation B in equation A
therefore
<u>The answer is</u>
The measure of arc FEH is equal to
Answer:
Step-by-step explanation:
We have two triangles and three rectangles.
The formula of an area of a triangle:
b - base
h - height
The formula of an area of a rectangle:
l - length
w - width
TRIANGLE:
b = 11 in, h = 7 in
RECTANGLE 1:
l = 11 in, w = 14 in
RECTANGLE 2:
l = 9 in, w = 14 in
RECTANGLE 3:
l = 8 in, w = 14 in
The Surface Area:
Substitute:
