The three inside angles of a triangle need to equal 180 degrees.
In a right triangle one of the angles is 90 degrees.
This means the other two angles need to equal 180-90 90 degrees.
You are given one of the angles of 52 degrees, so subtract that from 90 to find the third angle.
90 - 52 = 38 degrees.
The answer is A.
Their speeds are ' s ' and ' s+7 ' .
Since Joon is decreasing the size of the distance between them from one end,
and Gerace is decreasing it from the other end, the distance between them is
shrinking, and they meet when the SUM of their distances is 174 miles.
The sum of their speeds is (s) + (s+7) = (2s+7) m/h
They meet after driving for 2 hours, so
(2h) x (2s+7) m/h = 174 miles
Eliminate the parentheses: (4s + 14) = 174
Subtract 14 from each side: 4s = 160
Divide each side by 4 : s = 40
Their speeds are <em>40 mph </em>and <em>47 mph</em> .
<u>Check: </u>
40 mph for 2 hours = 80 miles
47 mph for 2 hours = 94 miles
80 + 94 = 174 miles yay !

Answer:
D
Step-by-step explanation:
Exterior means outside which means it has to be one of the angles outside the triangle.
Options A, B, and C have angles inside the triangle.
Option D is the only angle outside the triangle
