Answer:
1500
Step-by-step explanation:
STEP 1 900 = 60% × Y
STEP 2 900 =
60
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 60 we will arrive at:
STEP 3 Y = 900 ×
STEP 4 Y = 900 × 100 ÷ 60
STEP 5 Y = 1500
You have to give every thing that the problem says for me to be able to figure it out.
90 degrees
BCO = 66
The whole ABC is 180
So BCO and BDO = 90
Therefore BAO must = 90 degrees
