Answer:

$C = 28.9$

Step-by-step explanation:

Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.

Apply the trigonometric ratio formula to find m < C.

Adjacent side = 7

Hypotenuse = 8

Trigonometric ratio formula to apply would be:

$cos(C) = \frac{7}{8}$

$cos(C) = 0.875$

$C = cos^{-1}(0.875)$

$C = 28.9$

Either a pecan or walnut means you add the probabilities together

20% plus 35% equals 55%
