Hello! every triangle’s interior angles add up to 180. here would be how I solve this equation.

180-75-40=65 (find missing angle)
65+x=180 (supplementary angles)
180-65=x (substitution)
115=x (simplify)
x=115 (reflexive property of equality)

Answer:

<u>A. Vertex: (1, -8); x-intercepts: -1 and 3</u>

Step-by-step explanation:

The vertex is the point of the parabola. Basically, the part where the parabola 'scoops' up.

So the point where it scoops up is (1, -18)

The x-intercepts are the points where the line or shape touches the x-axis. The x-axis is the lines that goes from left to right.

The places where it touches the x-axis is -1 and 3

The diameter of a truck tire is 22inches Approximately how fat will the truck have traveled after 5 rotations of these tires

kvasek [131]

Answer:

The truck have travelled 345.5 inches after 5 rotations of the tires

Step-by-step explanation:

Given:

Diameter of the tyre= 22 inches

Number of rotations= 5

To find:

Distance travelled after 5 rotations=?

Solution:

We have given with diameter,

So let radius be r

r= $\frac{diameter}{2}$

$r=\frac{22}{2}$

r=11 inches

The distance covered by one rotation is given by circumference

Circumference = $2\pi r$

Substituting the values, we get

Circumference = $2\times\pi\times r$

Circumference = $2\times\pi\times 11$

Circumference = $2\times\3.14\times 11$

Circumference = $6.28\times 11$

Circumference = 69.11

Now for 5 rotation,

Distance travelled = $5\times(\text{circumference value})$

Distance travelled = $5\times(69.11)$

The truck will travel 345.5 inches.
