(a) 127.5 is what percent of 51 ?

1 answer:

8 0

To solve this, you need to divide 127.5 by 51:
127.5/51 = 2.5
To find the percent, multiply 2.5 by 100:
2.5 x 100% = 250%
So 127.5 is 250% of 51

How do I find the value of theta given to area of the sector and the radius

stira [4]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\quad 
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=24\\
A=90
\end{cases}\implies 90=\cfrac{\theta \pi 24^2}{360}\implies 90=\cfrac{\theta \pi 576}{360}
\\\\\\
90=\cfrac{8\theta \pi }{5}\implies 450=8\theta \pi \implies \cfrac{450}{8\pi }=\theta \implies \cfrac{225}{4\pi }=\theta \\\\\\ 17.904931 \approx \theta$

Find the measure of each angle.

motikmotik

Answer:

m∠2 = 98°, m∠3 = 82°

Step-by-step explanation:

I'm going to assume this is a straight angle

Supplementary angles

Supplementary angle are two angles that equal 180°

m∠2+m∠3=180°

<h3>-Substitute</h3>

m∠2+m∠2-16=196°

2m∠2=196°

<h3>Divide both sides by 2</h3><h3 />

m∠2=98°

Since we said m∠3 = m∠2 - 16°

m∠3 = 82°
