Answer:
x = - 1
Step-by-step explanation:
- 5x - 16 = 9x + x - 1
- 5x - 16 + 16 = 9x + x - 1 + 16
- 5x = 9x + x - 1 + 16
- 5x = 10x + 15
- 5x - 10x = 10x - 10x + 15
- 15x = 10x - 10x + 15
- 15x = 15
- 15x ÷ - 15 = 15 ÷ - 15
x = 15 ÷ - 15
x = - 1
Answer:
31°
Step-by-step explanation:
Transversal BD crosses parallel lines AB and CD, creating alternate interior angles ∠2 and ∠5. As you know, alternate interior angles are congruent, so have the same measure.
m∠5 = m∠2 = 31°
267.5
Step-by-step explanation:
cos(87) = 14 ÷ t
=tcos(87) = 14
t = 14÷cos(87)
= 267.5
Answer:
237 = m + 137
this is the equation showing the relationship
Step-by-step explanation:
a) You need a high degree of precision and accuracy to machine the gears because of what the device is meant to do: time-keeping.
b) You only need a fair degree of accuracy here for matching purposes.
c) Since you're measuring with a tape measure, you only need a fair amount of accuracy.
