2.5x4=10(Bert's walking distance)
22-10=12(Brenda's walking distance)
12/4=3
3km/h is Brenda's walking distance.
I think you mean 87 degree angle, but all you'd have to do is subtract 180 with 87, to get 93 degrees.
good luck
x
Answer:

Step-by-step explanation:
Notice that Angle A is being bisected.
Hence, we can use the Angle Bisector Theorem to write the following proportion:

Solve for x. Cross-multiply:

Distribute:

Subtract 14x from both sides:

Add 50 to both sides:

Divide both sides by 6. Hence, the value of x is:

11 divided by 5 is 2.2 and you multiply that by 2 1/4 which is 2.25 in decimal form. The answer is 4.95
