Answer/Step-by-step explanation:
✔️Reference angle = 50°
Opposite side length = y
Hypotenuse = 8 cm
Adjacent = x
Thus, applying CAH we can find x as shown below:
Cos 50 = adj/hyp
Cos 50 = x/8
8 × cos 50 = x
x = 5.1 (to 1 decimal point)
Thus, applying SOH, we can find y as shown below:
Sin 50 = opp/hyp
Sin 50 = y/8
8 × Sin 50 = y
y = 6.1 (to 1 decimal point)
Answer:
6cm
Step-by-step explanation:
To break down the steps back to radius, the formula is placed reversely in
Since 36 is without pie, square root is needed.
=6
Therefore, 6 cm is the radius.
