Help with Geometry needed!<br>For this figure, what is the value of X?

Finger [1]

Hello! A triangle has angles that sum up to 180°. So first off, let's solve for the angle of the other triangle. 83 + 31 gives us 114. 180 - 114 is 66. So the angle for the first triangle is 66°. The opposite angle would be the same. Finding the measurement of the other triangle gives us the measurement of x, because the angles are the same. So x = 66°.

What is the sector with a central angle of 185 degrees and a diameter of 6.4 m? Round to the nearest tenth.

mr_godi [17]

The area of a sector is
$A=\frac{1}{2}r^2\theta =\frac{1}{2}\left(3.2\:m\right)^2\left(185\cdot \frac{\pi }{180}\right)=16.5\:m^2$

The answer is 16.5 square meters.
