Assuming the house is parallel to the ground, your triangle is made up by the house, the ground, and the ladder. Using sin(x) = opposite/hypotenuse on the angle 70 degrees, you would have sin(70) = 20/x (because 20 is the side opposite of the angle connecting the ladder and the ground)
--> simplify sin(70) * x = 20 --> x = 20 / sin(70
--> substitute (and make sure your calculator in in degrees) x= 21. 284
Answer:
C. 
Step-by-step explanation:
The radius of the circle is 24 units, then the area of the whole circle is
The shaded circle is limited by 45° angle, so its area is
of the area of the whole circle.
The area of the shaded circle is
Answer:
416 miles
Step-by-step explanation:
78 divided by 3 = 26
26 x 16 = 416
Yes because 3×2= 6 , 3×5= 15, 15 + 6 = 21
