Since it is shown that 2 of the sides of the triangle are congruent, we can assume that they have the same angle measures.
so to solve for the missing angle you can set up an equation equal to 180 since all triangles add up to 180 degrees.
21 + 21 + x = 180
42 + x = 180
x = 138
the value of the missing angle should be 138 degrees

Answer:
32,000 square feet gross area and 28,750 square feet net area
Step-by-step explanation:
Given a rectangular site measures 125 feet (frontage) by 256 feet (depth), of which 26 feet is in the public right of way. We have to find the the gross and net site area.
As, 26 feet width is in the public right of way which excluded in the net area but included in gross area.
For gross area,
Length=125 feet
Width=256 feet

For net area,
Length=125 feet
Width=256-26=230 feet

Hence, last option is correct.
The answer is: 32,000 square feet gross area and 28,750 square feet net area
You can you 72 which would make 2/8 18/72 and 3/9 24/72 which makes the sum 42/72.
