Explain how you would find the perimeter of this triangle.

Answer:
Step-by-step explanation:
51+90=141.3
180-141.3=38.7
90+38.7+51.3
So 4 and a number equal 90 degrees.
51.3 degrees are the number of 4 and c^2
We can use the Pythagorean theorem to find out that a^2 is 16
16 and b^2 will equal c^2 or the missing angle for 51.3 degrees.
a=51.3
b=90 meaning it has a 38.7 more of an angle than the 4 on the bottom.
Meaning it will be 7.02
7.02+4=11.02
