This is the last one right?
Answer:
x = 18 units.
Area of triangle = 156 units^2.
Step-by-step explanation:
Area of the rectangle = 4(2x + 3) and the area of the triangle = 1/2*6*(3x - 2).
These are equal, so:
4(2x + 3) = 1/2*6*(3x - 2)
8x + 12 = 9x - 6
12 + 6 = 9x - 8x
x = 18.
Area of triangle = 1/2 * 6 * (3(18) - 2)
= 3 * 52
= 156 units^2.

The measure of a single angle of a triangle is not enough information to allow you to find any other angle or side length of the triangle. Is there more information or a figure?
If this triangle is a right triangle, and angle C is the right angle, then angle C measures 90.
The sum of the measures of the angles of a triangle is 180.
m<A + m<B + m<C = 180
We know angle A measures 48.
Angle C measures 90.
48 + m<B + 90 = 180
m<B + 138 = 180
m<B = 42
Answer:
The shorter piece is 24 inches long
Step-by-step explanation:
When cut into 2 pieces, the longer piece is 48 inches, twice the size of the smaller one, thus the answer is 24 inches
