Step-by-step explanation:
m<POR = 90°
=>m<POQ+m<QOR=90°
=>x+37°=90°
x=90°-37°=53°
option B
If AB = CD, then 3x+4 is equal to 4x-1
3x + 4 = 4x - 1
Add one to both sides to cancel out.
3x + 5 = 4x
Subtract 3x from both sides to cancel out.
5 = x
Now, substitute the 5 in place of the x in the equation for AB (3x+4)
3(5) + 4
15 + 4
19
Final Answer: B) 19
Answer:
Orginal Speed is 135
Step-by-step explanation:
The ratio of final speed: original speed is

We know that 90 km is it final speed so, we set up a proportion
