So QRS equals to 158 degrees. Therefore, you need to do 8x+8+2x=158. This is so then you can find x. In order to find x, you'll need to combine the 2x and 8x(10x+2=158). Then subtract 2 from both sides(10x=156). Finally divide by 10(x=15.6). In order to find TRS, multiply 15.6 by 2 to get the angle measure. If you want to find QRT, plug 15.6 into the equation(multiply 8 and 15.6 and add 8=132.8)
Answer:
What are you talking about? I didn't understand the question.
Answer: 1- quadrant 1 or top right
2- quadrant 4 or bottom right
3-quadrant 3 or bottom left
22% since 100-78 is 22 so that is the percentage of numbers between 78 and 100
X=(-10 ) Hope this helps!!! :)
