Answer 1

are those homeworks?

Answer 2

its problrems i dont understand

Answer 3

several easy problems !!they gona be assignment?

Answer 4

A whole revolution is 360 degrees, you can find x by adding up everything and set it equal to 360.

\((8x-10)+(6x)+(10x+10)=360\)

Answer 5

x is 15 right

Answer 6

you got it, x = 15 is correct

Now use this to find the angle measures of the triangle

Answer 7

\((8x−10)+(6x)+(10x+10)=360\)
Break up the parentheses.
\(\begin{align} 8x-10+6x+10x+10&=360 \\
24x&=360 \\
x&=15 \\ \end{align}\)
Yup that's right :)

Answer 8

what kind of triangle is it though?

Answer 9

are you familiar with the inscribed angle theorem?

Answer 10

no

Answer 11

the idea is that the angle PQR is half of the central angle POR where O is the center point of the circle

Answer 12

the central angle POR is equal to the arc measure of PR, so

arc PR = 6*15 = 90

which means that

m < PQR = (1/2)*90 = 45

This means that angle PQR is 45 degrees
