A similar problem, also involving an expression, is given at brainly.com/question/26142208
Answer:
x = 73
Step-by-step explanation:
x-5 = 68 due to parallel lines
?/8 = 3/?
Multiplying both sides by 8, then “?” gives
8? * ?/8 = 8? * 3/?
?*? = 24
The number, then, is sqrt(24), or 2 sqrt(6), which is approximately 4.90.
The missing number would be 28. 7*4=28.
