Answer:

  (b)  tan B = 8/6

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

Then angle B is involved in tangent and cosine relationships this way:

  tan B = 8/6 . . . . . . matches 2nd choice

  cos B = 6/10 . . . . . matches no choices

_____

<em>Additional comment</em>

Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.

Equation<br> 2x-1/4+x/3=2
Elena L [17]

Answer:

x=27/28

Step-by-step explanation:

Let's solve your equation step-by-step.

2x−14+x3=2

Step 1: Simplify both sides of the equation.

2x−14+x3=2

2x+−14+13x=2

(2x+13x)+(−14)=2(Combine Like Terms)

73x+−14=2

73x+−14=2

Step 2: Add 1/4 to both sides.

73x+−14+14=2+14

73x=94

Step 3: Multiply both sides by 3/7.

(37)*(73x)=(37)*(94)

x=27/28

Answer:

x=27/28

Your weekly base salary is $150. You earn $20 for each phone you taht you sell. The company policy is that as a part-time employ
Eduardwww [97]

Answer:

You can sell at least 40 phones each week.

Step-by-step explanation:

Given that:

Weekly base salary = $150

Earning on each phone = $20

Maximum amount that can be earned each week = $950

Let,

m be the number of phones.

20m + 150 ≤ 950

20m ≤ 950 - 150

20m ≤ 800

Dividing both sides by 20

\frac{20m}{20}\leq \frac{800}{20}

m ≤ 40

Hence,

You can sell at least 40 phones each week.

Which side of angle measures could be the interior angles of a triangle?
jok3333 [9.3K]

The sum of all the angles of a triangle is 180 degrees.

If you add 90 + 90 + 90 together you get 270. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.

If you add 80 + 80 + 200 together you get 360. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.

If you add 40 + 50 + 60 together you get 150. These can not be the angle measures of interior angles of a triangle because the sum is less then 180.

If you add 15 +30 + 135 together you get 180! This set of angle measures can the be interior angles of a triangle!

Hope this helped!
