This is number one in a 15 question test. teacher said we could get anse=wers online so by tomorrow around 6: 00 am . carmen is practicing her free throws. she made 3/8 of the shots she took at basketball practice today. part a use long division to find the decimal equivalent of 3/8. part b carmen knows that 1/4 = 0.25. explain how she could use this fact to determine the decimal equivalent of 3/8.

step-by-step explanation:

b and c

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.
