The distance between city A and city B is 22 miles. The distance between city B and city C is 54 miles. The distance between city A and city C is 51 miles. What type of triangle is created by the three cities?

A - an acute triangle, because 222 + 542 >512
B - an acute triangle, because 222 + 512 >542
C - an obtuse triangle, because 222 + 542 >512
D -an obtuse triangle, because 222 + 512 >542

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

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.

3+3+3+2*2*2+29*12 = 365
