Answer:

Step-by-step explanation:

since it is an isosceles triangle other two angles are 45 and 45 degree.

take 45 degree as reference angle

using sin rule

sin 45=opposite/hypotenuse

1/ $\sqrt{2$ =x/ $\sqrt{12$

do cross multiplication

x $\sqrt{2$ = $\sqrt{12$

x= $\sqrt{12$ / $\sqrt{2$

x= $\sqrt{3$

Find the area of the blue shaded region. Round your answer to the nearest hundredth.

SSSSS [86.1K]

Answer:

173.01

Step-by-step explanation:

To area of a sector or portion of a circle is found using:

$A = \frac{N}{360} \pi r^2$

Substitute N = 50 and A = 27.93.

It becomes $27.93 = \frac{50}{360} \pi r^2\\27.93 = 0.139 \pi r^2\\200.94 = \pi r^2$

The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.

200.94 - 27.93 = 173.01
