That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse
Hope this helps!
Answer: 294.4 m²
<u>Step-by-step explanation:</u>
Separate the shaded region into two parts:
- The section containing the central angle of 230° (360° - 130°)
- The triangle with sides 11.1, 11.1 & 20.12 (use Law of Cosines)


Area of shaded region = Area of (1) + Area of (2)
= 247.3 + 47.1
= 294.4
♥ 7/12 in fraction is 7/12.
♥ In decimal it is <span>0.583333</span>
When the dilation is about the origin, the scale factor multiplies every coordinate. That is (considering the x-coordinate) ...
6·k = 3
k = 3/6 = 1/2
The appropriate choice is
1. 1/2
Will there's
5.5 x 2 = 11
hope that helped
