[SPLIT] Suppose <T and <U are complementary. Find M &a

[jordann_125]

Suppose <T and <U are complementary. Find M<T ("the measure of angle T") and M<U if M<T = 16x - 9 and M<U = 4x + 9

I know the answer is 67.8°, but I don't know how to get it.

It would be like 20x + 0 = 90 so you'd divide by 20 and get 4.5 so 16*4.5 then - 9 right but i got like 63 not 67.8??? What am i doing wrong?

using the information you provided, 67.8 is incorrect.

(16x-9)+(4x+9) = 90
20x = 9
x = 4.5

16(4.5) - 9 = 63
4(4.5) + 9 = 27

63+27 = 90 ... it checks
