Answer:

see below

Step-by-step explanation:

Vertical angles are equal

2x = 68

Divide by 2

2x/2 =68/2

x = 34

20+160 = 180

And we know that supplementary angles add to 180

so 20 and 160 are supplementary angles

Two sides and an angle are given. determine whether the given information results in one triangle, no triangle, three triangles,
Crazy boy [7]
We are given 2 sides 18.7, 16.1 and a NON-included angle.
We have to calculate the altitude of the triangle.
altitude = 18.7 * sine (35)
altitude = 18.7 * 0.57358
altitude = <span> <span> <span> 10.725946 </span> </span> </span>
In this case, side c is greater than the altitude and is less than side a so 2 two triangles will be formed.

Write an equation that relates the time, t, it takes to travel a given distance, d.
brilliants [131]

The equation that relates the time, t, it takes to travel a given distance, d is d = rt

<h3>What is Speed?</h3>

This is a scalar quantity and can be defined as  the magnitude of the rate of change of its position with time.

d = rt

where d is distance, r is speed or rate, t is time.

We can calculate the time by dividing the distance with the rate (speed).

t =  d/r

This is why it was chosen as the most appropriate choice.
