Answer:

D. 68 degrees

Step-by-step explanation:

Remember, the total degree of a triangle is 180 degrees, not 360 like a rectangle.

To solve, set up an equation.

$y+(y-12)+56=180$

Solve:

$2y+44=180$

Subtract 44 from both sides

$2y=136$

Divide both sides by 2

y=68

I hope this helps!

Answer:

Step-by-step explanation:

The sum of the angles of a triangle add to 180

y + y-12 +56 = 180

Combine like terms

2y+ 44 = 180

Subtract 44 from each side

2y+44 = 180-44

2y = 136

Divide by 2

2y/2 = 136/2

y = 68

Suppose segment PQ has one endpoint at P (0,0). If T (6,3) is a point 3/10 of the way from P to Q, find the coordinates of Q.

mixer [17]

Answer:

Q(20,10)

Step-by-step explanation:

If point T (6,3) is a point 3/10 of the way from P(0,0) to Q(x,y), then

$\overrightarrow {PT}=\dfrac{3}{10}\overrightarrow {PQ}.$

Find the coordinates of the vectors $\overrightarrow {PT},\ \overrightarrow {PQ}:$

$\overrightarrow {PT}=(6-0,3-0)=(6,3);\\ \\\overrightarrow {PQ}=(x-0,y-0)=(x,y).$

Thus,

$(6,3)=\dfrac{3}{10}(x,y),\\ \\(x,y)=\dfrac{10}{3}(6,3)=(20,10).$

Answer:

28 ft below the surface.

Step-by-step explanation:

A scuba diver was 53 below the oceans surface. If he rises 25 feet, what is the new depth?

You subtract 25 ft from 53 ft leaving you with 28 ft.

53 ft

- 25 ft

28 ft below the surface
