So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
Answer:
Step-by-step explanation:
2x+32=8
2x=-24
x=-12
Since angle 2 is 120 degrees, the corresponding angle is 6, so 6 will also be 120 degrees
6 and 8 should form 180 degrees
180 - 120 = 60
so angle 8 is 60 degrees
Answer:
254.47 m or B
Step-by-step explanation:
First you find the area of the circle and then you subtract it from the area of the square to get your answer.
