Question

okay so i have to find x on a complementary angle it is 6x and 5x-20 can you explain please?

Answer 1

if two angles are complementary, then they add up to 90 degrees
so if one of your angles is 6x and the other is 5x-20, then we have:

6x + 5x - 20 = 90

Answer 2

you just need to solve this to find x

Answer 3

do you understand?

Answer 4

trying to so i would actually take the 20 from the 90? and then try to find the answer?

Answer 5

not quite. you need to ADD 20 to both sides of the equation.

Answer 6

so you would get:

6x + 5x - 20 + 20 = 90 + 20
6x + 5x = 110

Answer 7

so x is 10 right?

Answer 8

perfect - well done!

Answer 9

ty you made it easy to understand

Answer 10

I'm glad I could help :-)
