answer is 1/10
Answer:
m<R = 22.62°
Step-by-step explanation:
Reference angle = R
Opposite = 5 cm
Hypotenuse = 13 cm
Apply the trigonometric function SOH:
Sin R = Opp/Hyp


R = 22.6198649°
m<R = 22.62° (nearest hundredth)
Answer:
151.62
Step-by-step explanation:
You just have to multiply the lengths of all the edges:
9 1/2 * 4 1/5 * 3 4/5 =
151.62
Answer:
-25
Step-by-step explanation:
Substitute r = 2 in the equation.
-9(2) - 7 = -18 - 7 = -25
Yes its true because a straight line is a 180 degrees angle
