Answer: ∠ACB= 60°, ∠DCE= 65°, ∠BCD= 55°
Step-by-step explanation:
1) Since ΔABC is an equilateral, we know ∠ACB= 60°
2) Since we know ΔCDE is an isosceles, we know that ∠DCE= 1/2 (180-50), which is 65°
3) We can add the 2 angles and then subtract them from 180 degrees to get ∠BCD= 55°
Answer:
D
Step-by-step explanation:
Since Alyssa wants to know her gas mileage, which is MILES PER GALLON, she will need to divide total miles by total gallons.
"per gallon" means per 1 unit of gallon, which we will get ONLY IF WE DIVIDE by TOTAL NUMBER OF GALLONS, hence we get "per unit of gallon".
<u>So we need to divide 243.8 miles by 7.71 gallons to get Alyssa's gas mileage.</u>
Answer choice D is right.
