Answer:
∠ B = 126°
Step-by-step explanation:
Since the lines are parallel, then
∠ A = ∠ B ( alternate angles ), thus
8x + 78 = 2x + 114 ( subtract 2x from both sides )
6x + 78 = 114 ( subtract 78 from both sides )
6x = 36 ( divide both sides by 6 )
x = 6
Thus
∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°
I believe it should be ∆LKD because the parts should correspond with each other. D is a right angle in the first triangle and appears in the middle, so since K is the right angle of the second, it should also go in the middle.
I believe this is proven by HL because both hypotenuses are congruent, as is a pair of legs, and they are both right triangles.
Answer:
19.685
Step-by-step explanation:
Answer:
0.77
Step-by-step explanation:
From the information given:
The breakdown time (a)= 3 hours
The breakdown rate (λ) = 1/a = 1/3
Average flow time in the system (W) = 2.305 hours
For the entire system;
The average down machines L = Wλ
= 2.305 × (1/3)
= 0.77
