Since the triangle is equilateral (you can tell by the tick on each side), all angles have the same measure as well.
The angles of a triangle sum up to 180 degress, so three equal angles must measure 60 degrees each.
So, in particular, we have
7x + 4 = 60 7x = 56 x = 8
Answer:
The area of the window will be equal to 195 sq. inches.
Step-by-step explanation:
On a boat, a cabin's window is in the shape of an isosceles trapezoid.
The longer side parallel side is at the bottom.
The top side of the trapezoid is 10 inches and the height is 15 inches and the base of the triangle formed from the height on the right is labeled 3 inches.
So, the bottom parallel side has length of (10 + 3 + 3) = 16 inches.
Therefore, the area of the window will be equal to
sq. inches. (Answer)
