What is the value of x in this triangle?

1 answer:

8 0

Since it's a right triangle, we can use SOH-CAH-TOA. So tan(x) = opposite/adjacent = 5/20
tan(x) = 1/4 = 0.25
x = arc-tan (0.25) = 14.04°

Answer:

119 $\frac{4}{7}$

Step-by-step explanation:

10 + 12 + 15 + 24 + 12 + 10 + 35 = 118

$\frac{1}{7} + \frac{2}{7} + \frac{3}{14} + \frac{1}{14} +\frac{2}{7} + \frac{1}{7} + \frac{3}{7} = \frac{11}{7}$

118 + 1 $\frac{4}{7}$

119 + $\frac{4}{7}$

$119\frac{4}{7}$
