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
Answer:
10 makes this equation true
Step-by-step explanation:
2x -4 = 16 /+4
2x= 20 /÷2
x= 10
Test
2(10) - 4 = 16
20 - 4 = 16 Correct
