Tom is GODEEPER
triangle with side lengths a, b, and c. How much greater is the perimeter
of a triangular field with sides that measure 33 yards, 56 yards, and
65 yards than the perimeter of a triangular field with sides that measure
19.
The formula P= a + b + cgives the perimeter P of a
26 yards, 49 yards, and 38 yards? (6.EE A.20)

ok

step-by-step explanation:

do i do it on a graph?

step-by-step explanation:

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.
