Answer:
Step-by-step explanation:
mP=5x-14
mQ=x-5
mR=2x-9
we know that all the angles in a triangle= 180
that means (5x-14)+(x-5)+(2x-9)=180
5x-14+x-5+2x-9=180 we add the variables and the numbers
8x=180+28
8x=108
x=26
mP=130-14=116
mQ=26-5=21
mR=43
Answer:
A
Step-by-step explanation:
imagine the shape is flipped and standing up. that's how you can compare both images.
is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)
(or 30 degrees)
sin
33% because 66/200 is .33, and convert that to percentage by multiplying by 100
