3. Triangle ABC has angle measures as shown.
(x + 2)
(6x + 10)
(a) What is the value of x? Show your work.
(b) What is the measure of angle B? Show your work.

Below in bold.

Step-by-step explanation:

(a) The angles in a triangle add up to 180 degrees, so:

x + x + 2 + 6x + 10  = 180

8x + 12 = 180

8x = 168

x = 168/8 = 21 degrees.

(b)  Angle B = x + 2

= 21 + 2 = 23 degrees.

y do u put "subscirbe to ence" on a app for ppl who need with their work?

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
