The interior angles of a triangle all add up to 180 degrees.
You know two of those angles. They are 26 degrees and 90 degrees. The little square thingy in the corner means that angle is 90 degrees.

Using the info above, you can set an equation for the missing angle INSIDE the triangle. Please keep in mind, the x in this equation does not represent angle L.
26+90+x=180
116+x=180
x=64

Now that we know the missing angle inside the triangle, you can find angle L. Angle L and the angle we just found are supplementary, because they are on a line. Supplementary means they add up to 180 degrees.

So, you can make an equation.
64+L=180
L=116

Angle L is 116 degrees. Sorry for the long answer!

A trampolinist steps off from 15 feet above ground to a trampoline 13 feet below. The function h (t) = -16 t 2 + 15, where t rep
kondor19780726 [428]

Answer:

Trampolinist will land on the trampoline after 0.9 seconds.

Step-by-step explanation:

The function h(t) = -16t² + 15 represents the relation between height 'h' above the ground and the time 't' of the trampolinist.

We have to find the time when trampolinist lands on the ground.

That means we have to find the value of 't' when h(t) = 15 - 13 = 2

[Since trampoline is 2 feet above the ground]

When we plug in the value h(t) = 2

2 = -16t² + 15

2 + 16t² = -16t² + 16t² + 15

16t² + 2 = 15

16t² + 2 - 2 = 15 - 2

16t² = 13

\frac{16t^{2}}{16}=\frac{13}{16}

t^{2}=\frac{13}{16}

t = \sqrt{\frac{13}{16}}

t ≈ 0.9 seconds

Therefore, trampolinist will land on the trampoline at 0.9 seconds.

What is the definition of right angles and straight angles?
Natasha_Volkova [10]

Answer:

Right Angle- an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.

Straight Angle-A straight angle is 180 degrees. This is a straight angle.

Step-by-step explanation:

180 is a straight angle and 90 is a Right angle

Find the area of the circle <br><br> r = 6 ft
Andru [333]

If the radius of the circle is 6 feet. Then the area of the circle will be 113.097 square feet.

<h3>What is a circle?</h3>

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

The radius of the circle is 6 feet.

Then the area of the circle will be

Area = πr²

where r is the radius of the circle. Then we have

Area = π × 6²

Area = 36π

Area = 113.097 square feet

More about the circle link is given below.

Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet
hichkok12 [17]

Answer:

Set up your height equation, then factor or use quadratic formula to find when h(t)=0

Step-by-step explanation:

Your equation will be -16t^2+vt +h where v is the initial velocity and h is the starting height. Now either factor or quadratic equation, whichever is easier for you.

Remember that the ball is on the ground when h(t)=0 since that is the height. There will be two zeros,  one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.
