<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
The area of the shaded regions is: 44π
<h3>What is the Area of a Circle?</h3>
Area of a circle where "r" is the radius is determined using the formula: πr².
The figure given has three circles, namely:
- Circle A with radius of 8 cm.
- Circle B with radius of 4 cm.
- Circle C with radius of 2 cm.
The area of the shaded regions = <em>Area of circle A - Area of Circle B + Area of Circle C</em>
Area of Circle A = (π)(8)² = 64π
Area of Circle B = (π)(4)² = 16π
Area of Circle C = (π)(2)² = 4π
Thus:
The area of the shaded regions = 64π - 16π + 4π
The area of the shaded regions = 44π

Answer:
the answer is −28
Step-by-step explanation:
C becuase it makes the most sense
Answer:
AB and CD
<A = <C
This is given information, but everything on this might or might not be congruent, since it has the same angles and side lengths.
It might be symmetrical along E and vertically downwards, but no garuantees since the image is a bit warped.
Step-by-step explanation:
A simple thing to remember is that the notches in the angle symbols and the sides mean that they are congruent. If a side has 2 notches, every other side that has 2 notches are congruent.
Angles and sides are not congruent of course, but angles that have the same number of notches are equivalent.
So with this in mind, we know stuff.
