Answer:

∡ZA = 66°

Step-by-step explanation:

Suplementary angles sum 180°

ZA + ZB = 180°

then:

(2x - 14)° + (3x-6)° = 180°

2x + 3x - 14 - 6 = 180

5x - 20 = 180

5x = 180 + 20

5x = 200

x = 200/5

x = 40

then:

∡ZA = (2x - 14)

∡ZA = (2*40 - 14)

∡ZA = (80-14)

∡ZA = 66°

Can someone help me im confused....PLZZZZ
lilavasa [31]

Answer:

see explanation

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width )

perimeter of rectangle A = 2(7) + 2(5) = 14 + 10 = 24 in

perimeter of rectangle B = 2(4x - 3) + 2x = 8x - 6 + 2x = 10x - 6 in

Equating the two gives

10x - 6 = 24 ( add 6 to both sides )

10x = 30 ( divide both sides by 10 )

x = 3

Thus

length of rectangle B = 4x - 3 = 4(3) - 3 = 12 - 3 = 9 in

Width of rectangle B = x = 3 in

#6: 7

#7: 7.3

#8: 15

#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4

#10: Round 2.5 to 3. 36/3 = 12

#11: If they want you to round 0.25 down to 0, then 7/0 is undefined. 

#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3

#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.
