1 answer:
-Dominant- [34]3 years ago
4 0

Step-by-step explanation:

  1. Since,in question 21 the trspezium is an isoseles tapizium
  2. therefore,9x-17=4x+28
  3. 5x=45
  4. x=9
  5. therefore q=9x-17
  6. =9*9-17
  7. =81-17
  8. q=64
  9. therefore 2t=360-128(since its isoseles triangle therefore adjacent base angles are equal)
  10. 2t=23
  11. t=116
  • In question 28
  1. 2(K+M)=360
  2. 2(3x+16 + 11x-18)=360
  3. 2(14x-2)=360
  4. 28x-4=360
  5. 28x=364
  6. x=13
  7. J=K
  8. Isoleses angles are equal
  9. 3x+16=J
  10. 39+16=J
  11. J=55
  • In question 29
  1. Bd=Ec (Congeruent sides of congurent trisnle are equal,BED~=CDE)
  2. 8x-27=2x+33
  3. 6x=60
  4. x=10
  5. Therefore,Bd=8x-27
  6. Bd=80-27
  7. Bd=53

Can someone help with this question? thanks
Licemer1 [7]

Answer:

Regular: C & E

Irregular: A & B

Not a polygon: F & D

Step-by-step explanation:

A polygon is a close sided shape with no curves. Since F and D have curves they are not polygons. Regular polygons have side lengths which are all equal to each other. C and E are regular polygons. Irregular polygons are polygons whose sides have different values from each other. A and B are irregular.

Marina spent $13.50 at the grocery store. She bought pears, kiwis, and pineapples. Pears cost $0.50 each, pineapples cost $1.50
MArishka [77]

Answer:

Number of pineapples= 10

number of pears = 19

number of kiwis = 10 -2 = 8

Step-by-step explanation:

Cost of a pear = $ 0.50

Cost of a pineapple = $ 1.5

cost of a kiwi = $ 0.3

Let the pineapples = p

Number of pears = 9 + p

Number of kiwis = p - 2

The cost is

0.15 p + 0.5 (9 + p) + 0.3 (p - 2) = 13.50

0.15 p + 4.5 + 0.5p + 0.3 p - 0.6 = 13.50

0.95 p = 9.6

p = 10
