Question

measure of angle T = (5x-10)
find the complement of angle T and
find the supplement of angle T? please help i dont understand

Answer 1

Let

C = complement of angle T
S = supplement of angle T

Answer 2

if two angles are complementary, then they add to 90 degrees

so because T and C are complementary, we know that

C+T = 90

solving for C, we get

C = 90 - T

I subtracted T from both sides. Do you see what comes next?
