PLEASE HELP ME FIND THE MISSING LENGTH ITS URGENT .

37

Step-by-step explanation:Using the Pythagorean Theorem, a ² + b ² =c ², you substitute the values for a and b with 12 and 35. This makes your equation 12 ² +35 ² = c ² . You then add 12 ² with 35 ² and that gives you 37 ² = C ² . You find the square root of both sides which is 37=C, giving you the length of C.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

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.
