Hello! Please may someone explain this question to me?

10°

Step-by-step explanation:

Triangle BDC is an isoceles triangle

180-30=150

150÷2=75

Then triangle ADC

75+30+65=170

180-170=10

ΔBDC is isosceles, meaning the two base angles are equal. to find them you need to:

180 - 30 = 150 ÷ 2 = 75. so , each of the base angles is 75°

∠BDC + ∠BCD = ∠ABD

30 + 75 = 105°

so, x = 180 - (105+65) = 10°

you will understand better if you draw the figure and fill in all the angles following my explanation.

x = 10°

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
