The smaller angle would be 60 degrees. Supplementary angles add to 180, meaning that 2:1 proportion would be 120:60 (3 parts, 180/3 = 60, 60 x 2 = 120).

Solve for x. round your answer to the nearest tenth

Answer:

13.8

Step-by-step explanation:

Hello There!

Basic concept: Geometry

We can solve for x using trigonometric ratios

Here are the Trigonometric Ratios

Remember SOHCAHTOA

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Adjacent

For the angle that has a measure of 37 degrees

We are given its adjacent side length (11) and we need to find the hypotenuse

Basic concept: Alegbra 1

Adjacent and Hypotenuse corresponds with Cos so we are going to use cosine to create an equation and solve for x

Remember cos = adjacent over hypotenuse

$cos37=\frac{11}{x}$

now we solve for x

what we want to do is get rid of the 11, to do so we divide each side by 11

$\frac{11}{cos37} =x\\cos37=.79863551\\\frac{11}{0.79863551} =13.773749224$

we're left with x = 13.773749224

finally we want to round to the nearest tenth

The answer would be 13.8
