Answer for 5

98.61, 107.18

Step-by-step explanation:

Tan 64 = opposite/hypotenuse

Opposite is the dimension of line facing the angle

Adjacent is the other dimension

Tan 64 = x/42

x = (tan 64)42

x = 42(2.3478603092) = 98.61

To get y

Sin 64 = opposite/hypotenuse

Hypothenus is the longest side

Sin64 = 98.61/y

y sin 64 = 98.61

y = 98.61/ sin 64 = 98.61/0.92002603819

y= 107.18174911 = 107.18

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
