In a triangle, the measure of the first angle is three times the measure of the second angle. The measure of the third angle is

75º more than the measure of the second
angle. Use the fact that the sum of the measures of the three angles of a triangle is 180° to find the measure of each angle.

The measure of the first angle is°?
The measure of the second angle is º?
The measure of the third angle is °?​

Answer:

equation 1

y = -2x

equation 2

y = x-3

Solution to both

(1,-2)

Step-by-step explanation:

We need to get the equations of both lines

General form is;

y = mx + c

where m is slope and c is the y-intercept

Table 1

since we have a point 0,0; the y-intercept here is zero

Let us get the slope. We can do this by selecting any two points

m = (y2-y1)/(x2-x1)

m = (2-10)/(-1+5) = -8/4 = -2

So the equation of the first line is;

y = -2x

Table 2

we get the slope

m = (4+2)/(7-1) = 6/6 = 1

The partial equation is;

y = x + c

To get c, we select any two point and substitute

4 = 7 + c

c = 4-7

c = -3

So the equation is;

y = x-3

To get the solution to both systems, we equate the y

-2x = x - 3

-2x-x = -3

-3x = -3

x = -3/-3

x = 1

To get y, we substitute;

recall; y = -2x

y = -2(1)

y = -2

Solution to the system is;

(1,-2)

Angles 8th grade math
fiasKO [112]
Yeah... I'm normal good at angles, but the way you've taken the picture, it's pretty hard for us to figure out. All you need to do is grab you protractor and start measuring. Pretty simple.<span />

During a huge snowstorm in the white mountains last year, it snowed 62.5 cm in one day. how much did it snow in meters?
makkiz [27]
Cm is a centimeter, which is one-hundredth of a meter. Or rather, one hundred centimeters is equal to one meter.

To convert cm to meters

(62.5 cm) * (1 meter/100 cm) = .625 meters

How do you solve 2sin^2θ = 1 ?
Murrr4er [49]

The value of θ is 45 degrees as sin45° is equal to 1/√2.

<h3>What is trigonometric equation?</h3>

Trigonometric equation refers to an equation consists of a number of trigonometric ratios whose angle is unknown.

<h3>What is the ranges of trigonometric angle?</h3>

Generally trigonometric angles are represented by θ. while solving equations we get the values of θ ranges from 0 degree to 90 degrees.

Given, 2sin²θ = 1

solving the equation

      sin²θ = 1/2

     sinθ = 1/√2

we know sin45° has a specific value 1/√2

   sinθ = sin 45°

now, θ = 45°

hence, the solution is θ = 45 degrees.
