Answer:
a=8
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
