We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5

We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°

This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°

Answer:

B. y = \frac{2}{15} X + 2

Step-by-step explanation:

I. Given x = 15 and y = 4

         4 = \frac{2}{15}(15) + 2

         4 = 2+2

         4 = 4 true

II. Give x = 0 and y = 2

         2 = \frac{2}{15}(0) + 2

         2 = 0 + 2

         2 = 2 true

III. Given x = -15 and y = 0

         0 = \frac{2}{15}(-15) + 2

         0 = -2 + 2

        0 = 0 true

Good luck.

Can someone please help me
belka [17]

Answer:

D

Step-by-step explanation:

First we need to figure out how many people are going on the field trip

if each class has 27 people going and there are 6 classes, 6*27=162

162 ppl are going. If 3 buses can hold 48 ppl then 3*48=144

3 buses are not enough, if we were to bring in one more bus 4*48=192

there would be enough place for everyone

The answer #6 is j. 100. He uses the treadmill for 40% so that means 60% of his exercise is not on the treadmill. 

40%= 40 mins 
60%= 60 mins
 total: 100%= 100 mins.
Hope this helps!

sergeinik [125]

Step-by-step explanation:

Equations:

Quantity:: d = n + 3

Value::: 10n + 5d = 615 cents

-------------------------------------------

Modify::

d - n = 3

d + 2n = 123

--------------------------------------------

Subtract and solve for "n"::

3n = 120

n = 40 (# of nickels)

d = n+3 = 43 (# of dimes)
