Answer: 110°
<u>Step-by-step explanation:</u>
∠A ≅ ∠B
since ∠A = 35° (given), then ∠B = 35°
Use the Triangle Sum Theorem to find ∠C:
∠A + ∠B + ∠Q = 180°
35° + 35° + ∠Q = 180°
70° + ∠Q = 180°
∠Q = 110°
The central angle (∠AQB) ≅ arc AB
since ∠AQB = 110° (solved above), then arc AB = 110°
Answer:
3.62
Step-by-step explanation:
Let
x = cost of cereal
y = cost of milk
5x + 2y = 31.24
x = $4.80
Substitute into the equation
5x + 2y = 31.24
5(4.80) + 2y = 31.24
24 + 2y = 31.24
2y = 31.24 - 24
2y = 7.24
y = 7.24 / 2
y = $3.62
Therefore,
1 gallon of milk cost $3.62
Answer:
One hour and 20 minutes.
Step-by-step explanation:
The angles in a isosceles triangle add up to 180 degrees.
so 180 degrees take away 36 degrees = 144 degrees.
base angles in a isoceles triangle are equal so 144 divided by 2 = 72 degrees.
so to find out y you do 360 - 72 = 288 degrees
therefore y = 288degrees
