Answer:
34 degrees and 56 degrees
Step-by-step explanation:
As the two given angles are complementary,
2x-10+3x-10=90
5x-20=90
5x=90+20=110
x=110/5=22
x=22
Now each angle
2x-10=2*22-10=34 degrees
and
3x-10=3*22-10= 56 degrees
What is x in this situation?
B. The y-intercept is 0 so it can't be C or D and the slope is 5/1. How I remember this is rise/run. Hope this helps!
There are 15 novelists and 9 poets. This is a ratio of 5 to 3 and adds up to 24 people
I would convert -2pi / 3 to degrees first by multiplying by 180degrees / pi. It equals 120 degrees.
120 degrees is in quadrant II, which is 90 degrees plus 30 degrees. It is 60 degrees from the 180 degrees.
So the reference triangle you use is 60 degrees.
Cos60 = 0.5
sin60 = sqrt(3) /2
But in quadrant II the only trig ratio that's positive is sin; all others are negative.
So cos120 = -0.5
sin60 = sqrt(3) /2
