Answer:

A= 150°

B=30°

C=150°

Step-by-step explanation:

Since a line is 180°, you can write an equation for C. C+30°=180° , from here use algebra to find C. The value of C will be 150°. When the value of C is 150° , since they're supplementary angles, the value of A will also be 150°.

Important thing to note:

The value of all these angles combined together is 360°.

kifflom [539]

Convert all into a fraction and you will get 115/100+1/50+47/40
So your answer is 469/200 or 2.345 as a decimal

Hey smart cookie ;)

So with this all we need to do is factor the expression.
Our answer is going to be 2x(16x^4+15)

Let me know if you have other questions!
Have a terrific day.

Find the area of this sector

slavikrds [6]

Answer:

1492.885

Step-by-step explanation:

the whole circle has 360° and an area of pi*r² =pi*24²=pi* 576

for 360° and A=pi*576

for 360-63= 297° and A= (297*576*pi) / 360 = 1,492.885 m²
