Answer:

D. 43 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180°. If x represents the measure of the third angle, then ...

75° +62° +x = 180°

137° +x = 180° . . . . . . . . . collect terms

x = 180° -137° = 43° . . . . subtract 137° from both sides of the equation

The third angle measures 43°.

2. Find an equation for the line with slope = 0 that passes through the point (-5, 7).

mel-nik [20]

Answer:

2. y = 7

3. x = 4

Step-by-step explanation:

Slope 0 is when the line is horizontal.. has a constant coordinate

(-5,7) lies on the line so the x-coordinate is 7

Equation: y = 7

A vertical line has all same x-coordinates.

Since (4,-2) is on the line, every point had x-coordinate of 4.

Equation: x = 5

Ms. Peters drove from her home to the park

worty [1.4K]

It takes 15 minutes for Ms. Peter to drive from park to her home

Given :

from her home to the park at an average speed of 30 miles per hour and

returned home along the same route at an average speed of 40 miles per hour

it takes 20 minutes to travel

Convert 20 minutes in to hour (divide by 60)

20 minutes = 1/3 hour

We know that distance = speed x time

From home to park, distance = $speed \cdot time =30 \cdot \frac{1}{3} =10 miles$

So , distance between home and park is 10 miles

Now we calculate the time taken to return from park to home

$time taken =\frac{distance}{speed} =\frac{10}{40}=\frac{1}{4}\\$

Time taken is 1/4 hours. Convert it into minutes by multiplying by 60

$\frac{1}{4} \cdot 60=15$

So it takes 15 minutes for Ms. Peter to drive from park to her home
