ANSWER
The sum of m∠DEA and m∠AEB is 180°.
Reason: The sum of angles on a straight line is always 180°.
Group like terms to get,
Simplify, and get,
Divide both sides by 10 to get,
We substitute this value to get the required angles.
Step-by-step explanation:
a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?
answer for a: <em>$95 + $55 = $150</em>
b. Is there a proportional relationship between time and the cost of the cell phone plan?
answer for b: <em>There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55. </em>
c. What is the total cost for x months? (Write an equation for the situation.)
answer for c: <em>95 + 55x = y</em>
Answer:
The prince's crown had a greater ratio of red gems to purple gems.
Step-by-step explanation:
KING = 5 red / 8 purple
PRINCE = 4 red / 5 purple
Times the ratio for the king by 5
5(5) / 8(5) = 25/40
Times the ratio for the prince by 8
4(8) / 5(8) = 32/40
The prince has a greater ratio of red gems
Hope this is right, and sorry if it is incorrect. Have a good day!
Answer:
X = 66 y = 48
Step-by-step explanation:
base angles of an isosceles are the same so x is 66
Angles in a triangle add up to 180
66 + 66 = 132
180 - 132 = 48
