Looking at the triangle we see the angles:
58, x
We also see a right angle, therefore you now have:
90, 58, 0
All three angles of a triangle should have a total of 180 degrees, so we add the known angles and subtract the total from 180.
90 + 58 = 148
180 - 148 = 32
Therefore, x = 32 or C
Answer:
7.0 mi
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

step 2
Find the measure of a
Applying the law of sines

substitute the given values

solve for a

In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems,You can break one large area of the rectangle into several smaller boxes.
