Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)

In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians

So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2

Which of the following equations can be used to find the length of angle LN in the triangle below?

shtirl [24]

Answer:

Option A. $LN^{2}=33^{2}-11^{2}$

Step-by-step explanation:

we know that

In the right triangle MNL

Applying the Pythagoras Theorem

$MN^{2}=ML^{2} +LN^{2}$

substitute the values

$33^{2}=11^{2} +LN^{2}$

$LN^{2}=33^{2}-11^{2}$
