Answer 1

Hi Wasabi,

given that you need the answers quickly I will give you the answers but please read how I set them up so you are empowered for next time.

question 1: the circle graph in its entirety has 360 degrees. EA represents 26 % of the 360.

I set up a proportion of 26/100 as x/ 360. answer 93.6 degrees.

Question 2 an interior angle intercepting an arc is 1/2 the measurement.

So angle Q R S = 30 degrees.

I help this helps and you could follow.

Answer 2

All the angles sum up to 360* and that's 100%

Find 26% of 360

A.) 93.6°

The Inscribed angle is 1/2 of the Arc

B.) m∠QRS = 30°
