'of' means multiply
what number=x
123b is 0.4 of what
123b=0.4 times x
divide both sides by 0.4
307.5b=x
the number is 307.5n
That’s the 90 degree angle right
Answer:
C.
Step-by-step explanation:
Let's start with triangle RST. This is a 30-60-90 triangle, which means it has the relationship x - x sqrt(3) - 2x.
If RS is 2 sqrt(3), then ST must be 2 and RT must be 4.
Triangle QRT is a 45-45-90 triangle, which means it has the relationship x - x - x sqrt(2).
If RT is 4, then RQ must also be 4.
Answer: x = 4
