Question

If the measure of angle GAT equals 30° and GT equals 60 cm, find GA and ATsolve number 7

Answer 1

GA = 34.2

Step-by-step explanation:

7) m∠OAG = 40 degree

GO = 22

GA = ?

opposite = side opposite the angle = 22

hypotenuse = GA

So we would apply sine ratio (SOH):

sin 40 = opposite/hypotenuse

sin 40 = 22/GA

GA(sin 40) = 22

GA = 22/sin 40

GA = 22/0.6428

GA = 34.2
