Answer:
x = 17
Step-by-step explanation:
The sum of all angle measures in any triangle is 180 degrees.
- Thus, 23 + 5x - 18 + 90 = 180.
Step 1: Simplify both sides of the equation.
Step 2: Subtract 95 from both sides.
Step 3: Divide both sides by 5.
Step 4: Check if solution is correct.
Thus, x = 17.

1) 4a/5
a% of 80 = a% (80) = (a/100)(80) = 80a/100 = 4a/5
2) 17b/100 or 0.17b
17% of b = (17/100)(b) = 17b/100 [ = 0.17b ]
3) ab/100
a% of b = (a/100)(b) = ab/100
Im not sure this is right but i think they will meet during 12 minutes
