Answer:
a=8
Step-by-step explanation:
We know that the right triangle has a total angle of 90.
We already have 50 witch means 40 is missing.
The equation given is:
6a-8 but we will upgrade it by the information we have so now it’s 6a-8=40
One of the multiples of 6 is, 6x8=48
Remember that 8 will be taken off.
Solve:
48-8=40 (witch is what we where looking for)
This is further proof that a=8

-2y-(-8y-2) = -2y + 8y + 2 = 6y + 2
2(3x + 16) - 7x = 6x + 32 - 7x = -1x + 32 = 32 - x
-x + 6 + (-3) + x + (-4) = -x + 6 - 3 + x - 4 = 3 - 4 = -1
RQ × RP = RS × RT
9 × ( 9 + 13 ) = 11 × RT
9 × 22 = 11 × RT
Divide sides by 11
9 × 22 / 11 = 11 × RT / 11
Simplification
9 × 2 = RT
RT = 18
