PLEASE HELP ME WITH THESE MATH PROBLEMS PLEASEE IM BEGGING IM HORRIBLE AT MATH

9) x= 8

11) 16 in

12) H

13) 843 ft

Step-by-step explanation:

9) Using corollary 2, you would have (x+4)² = x(x+10)

Plug in the numbers and 8 should work

(8 + 4)² = 8 (8 + 10)

(12)² = 8(18)

144 = 144

11) 24/15 = 1.6

1.6 * 10 = 16

12) They are one the same side therefore they are same-side interior angles

Also since it's a trapezoid, the bottom and top are parallel

13) tan 34° = x/1250

Multiply both sides by 1250

1250 tan 34° = x

x = 843.1356461
