Answer:
Step-by-step explanation:
<A = <C
The angles meeting at B and are part of the triangle are vertically opposite and therefore equal.
<E and <D are equal. (given)
Therefore by angle angle angle, the two connected triangles are similar
AD/CE = 12/x from <A = <C
27/23.4=12/x Cross Multiply
27x = 12*23.4 Combine the Right Side
27x = 280.8 Divide by 27
x = 280.8/27
Answer: x = 10.5 cm
Answer:
10
Step-by-step explanation:
2(6+1) - |-10| + 3*2
= 2 (7) - (+10) + 6
= 14 - 10 + 6
= 20 - 10
= 10
34.4%
to turn a decimal into a percent you move the decimal two places to the right
if you needed to turn a percent into a decimal, you'd move the decimal two places to the left
Answer:
1830
Step-by-step explanation:

Answer:
<u>Each of the 4 sectors have an area:</u>
- πR²/8 - πr²/8, where
- R = 28/2 - 2 = 12 in
- r = 6/2 = 3 in
<u>Find the area:</u>
- A = π/8(12² - 3² ≈ 53 in²
<u>Outer perimeter of the frame:</u>
- P = d + πd/2 =28( 1 + π/2) ≈ 72 in
