A triangle has two sides of length 15 cm and 17 cm. Select all the values of its third side that would make it a right triangle
Natali [406]

Answer:

\sqrt{514} cm, 8cm, are both options

Step-by-step explanation:

For a right triangle one can find the length of the longest side by using the Pythagorean theorem. So there are two options I can think of that if the triangle is a right triangle will work. First remember what the Pythagorean theorem is : side a^2+side b^2=hypotenuse^2

The hypotenuse is the longest side of a right triangle. So if the sides that are 15 and 17 cm are not the longest sides then the formula would be:

15^{2} +17^2=c^2\\15^2+17^2=\sqrt{514}cm

But if 17cm is the longest side then:

a^2+15^2=17^2\\8^2+15^2=17^2\\a=8cm

Hope this helps!

2t + 8 is greater than or equal to -4 ( t + 1 ), whats the answer to the equation?
Natali [406]

Step-by-step explanation:

2t + 8 <u>></u> - 4( t + 1)

2t + 8 <u>></u> - 4t - 4

2t + 4t <u><</u> - 4 +8

6t <u><</u> 4

Divide both sides by 6

T <u><</u> <u>4</u><u> </u>

6

t <u><</u> <u>2</u><u> </u>

3

I think that is the answer

Hope it helps :)

What is the slope of the line that contains the points in the table?
bonufazy [111]

Answer:

D.2

Step-by-step explanation:

Slope is given by the ratio of change in y to change in x.

Taking two points on the table;

(-5, 15) and (1, 3)

Slope = (3-15)/ (1- (-5))

         = 12/6

         <u>= 2 </u>
