Answer:
m∠2 = 16° or 25°
Step-by-step explanation:
The sum of angles 1 and 2 is congruent to angle CED.
20° +(x^2)° = (9x)°
x^2 -9x +20 = 0 . . . . . divide by °, put in standard form
(x -5)(x -4) = 0 . . . . . . . factor
x = 5 or 4
m∠2 = (x^2)° = (5^2)° or (4^2)°
m∠2 = 16° or 25°
13:
A- The scale factor is 16 (80/5)
14:
A- The scale factor is 6 (30/5)
B- The perimeter of the scale drawing is 14 feet (5x2) + (2x2)
C- The area of the scale drawing 10 ft. sq (base x height) (5 x 2)
D- The perimeter of the actual screen is 84 feet (30x2) + (12x2)
E- The area of the actual screen is 360 ft. sq (base x height) (30 x 12)
Hope this helped you out tons! :D
Add 21 to both sides, so you get 9z = 81
Answer:
Step-by-step explanation:175.42x .20=35.08 35.08Divided by 11=3.19
so each would pay 3.19 tip
total each would pay for bill would be 175.42+35.08=210.50
210.50divided by 11 =19.14
Answer: 110
The 3 figures showed the same pattern by multiplying 2 consecutive whole numbers starting from one. Multiplying 1 by 2 gets 2, 2 by 3 gets 6, 3by 4 results to 12 and so on. If this pattern continues, then 4 will be multiplied by 5, 5 by 6, 6 by 7, 7 by 8, 8 by 9, 9 by 10, and lastly the 10th figure 10 by 11 which is equal to 110.
