The measure of angle B is 97°
Answer:
x divides by root(2)
Or
x times root(2) divided by 2
Step-by-step explanation:
The legs of the large right angle triangle:
xcos(45) = x/sqrt(2)
Or xsqrt(2)/2 units
I thought you said these problems were all different. They look exactly the same to me.
<span>Figure the volume of one of the small blocks, and use that to divide into the whole volume. </span>
<span>3 1/4 = 13/4 so the box has a volume of 13/4 * 3 * 1 = 39/4 ft^3 </span>
<span>each small block has a volume of (1/4)^3 = 1/64 ft^3 </span>
<span>(39/4) / (1/64) = 624
Hope this helps love.

Answer:
Area of sector = 144.4π cm²
Step-by-step explanation:
Given:
Perimeter of circle = 40π cm
Given angle = 130°
Find:
Area of sector
Computation:
Perimeter of circle = 2πr
⇒ 40π = 2πr
⇒ 40 = 2r
⇒ Radius r = 40 / 2
Radius r = 20 cm
Area of sector = [θ/360][π][r]²
⇒ Area of sector = [130/360][π][20]²
⇒ Area of sector = [0.361][π][400]
Area of sector = 144.4π cm²
