Part 1 of 2 Write the perimeter of the triangle as a simplified
polynomial. Then factor the polynomial.
4x² + 1
13x +4
X? + 13x
The perimeter of the triangle is (Simplify your answer.)

4x²+1 which is the answer

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

the diver is 33 feet below the surface.
