Answer:

1. x = 10

2. x = 8

3. x = 7

Step-by-step explanation:

1. Sum of Angles in a triangle = 180

(6x + 3) + (5x - 7) + 74 = 180

11x - 4 + 74 = 180

11x + 70 = 180

Subtract 70 from both sides

11x = 110

Divide both sides by 11

x = 10

2. (8x + 1) + (7x + 14) + 45 = 180

15x + 15 + 45 = 180

15x + 60 = 180

Subtract 60 from both sides

15x = 120

Divide both sides by 15

x = 8

3. We first have to get the 3rd angle: 180 - Exterior angle = 3rd angle

180 - 118 = 62

Now we can find the value of x

10x + (6 + 6x) + 62 = 180

16x + 68 = 180

Subtract 68 from both sides

16x = 112

Divide both sides by 16

x = 7

marshall27 [118]
Yes they are working at the same rate because 4x5=20 and 10 windows every four hours and 5x10= 50 so they are both working at the same rate. Or here is another answer, They are working at the same rate because one was doing 10 windows every four hours and one did 50 windows in 20 hours, so 4 x 5= 20 which is the amount of hours the other carpenter was doing so 5x10 for every four hours, and that equals 50 so they were both working at the same rate. Hope I helped :)
