Answer:
B) 135 degrees
A) 83 degrees
Step-by-step explanation:
Each interior angle of a regular octagon is 135 degrees large.
In question two, <1 is an inscribed angle. A circle has 360 degrees, so the intercepted arc of <1 is 166, so m<1=83.
Hope it helps <3

Answer:
<4 = 81
Step-by-step explanation:
we know that all the interior angles of a triangle will equal 180
so <1 + <2 + <3 = 180
we know that <4 is the exterior angle to <3
the exterior angle is equal to the angles opposite to its interior
<3 is the interior angle to <4
<1 and <2 are the angles opposite to <3
so <4 = <1 + <2
<4 = 42 + 39
<4 = 81
Answer:
2w^2 + 34w
Step-by-step explanation:
2w(w+17)
Multiply the 2w by each term in the parentheses
2w*w + 2w*17
2w^2 + 34w
Answer:
Find a common denominator on the right side of the equation.
Step-by-step explanation:
On the right side of the equation we began with
Then we ended with
As we can see, only the left term changed. It was multiplied by . This was done in order to match the denominator of the right term.
As you can see they now match.
