The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (4, 1) and (2, 5). Substitute:

m=\dfrac{5-1}{2-4}=\dfrac{4}{-2}=-2

<h3>Answer: The slope is -2.</h3>

Hello!

Explanation:

Slope-intercept form: → y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

Rise/run

\frac{rise}{run}

m=\frac{y^2-y^1}{x^2-x^1}

x^1,y^1=(4,1)

x^2,y^2=(2,5)

\frac{5-1=4}{2-4=-2}=-2

So the final answer is \boxed{=-2}

Hope this helps!

Thank you :)

Finishing the angles of the smaller triangle if E is 90 and F is 30 then G needs to be 180-90-30 = 60 degrees.

Angles G and C are supplementary angles which need to equal 180 degrees

Angle c = 180-g = 180-60 = 120

Angle c = 120 degrees.

Solve a triangle when A=15° B=113° and b=7?
JulsSmile [24]

Let us draw a triangle ABC with A=15° ,B=113° and b=7.

Please see the attached image.

We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have

A+B+C=180\\&#10;\\&#10;15+113+C= 180\\&#10;\\&#10;C=62^{\circ}

Apply Sine rule in the triangle ABC, we get

\frac{a}{\sin 15}= \frac{7}{\sin 113}\\&#10;\\&#10;a=\frac{7 \sin 15}{\sin 113}\\&#10;\\&#10;a=1.97\\&#10;\\&#10;\text{Again apply sine rule, we get}\\&#10;\\&#10;\frac{c}{\sin 62}= \frac{7}{\sin 113}\\&#10;\\&#10;c=\frac{7 \sin 62}{\sin 113}\\&#10;\\&#10;c=6.71

Therefore, we have

a=1.97\\&#10;c=6.71\\&#10;C=62^{\circ}

n the figures, ΔCDA ≅ ΔXYZ . Name the congruent angles. ∠C ≅∠Y, ∠D ≅∠X, ∠A ≅∠Z ∠C ≅ ∠Z, ∠D ≅∠Y, ∠A ≅∠X ∠C ≅ ∠X, ∠D ≅∠Y, ∠A ≅∠Z ∠

When writing the congruent triangles, the otder of the letters is EXTREMELY important.
This is because, each angle in the first triangle is congruent to its corresponding angle in the second triangle and each side in the first triangle is congruent to its corresponding sode in the second triangle.

Now, we are given that triangle CDA is congruent to triangle XYZ.
Based on the above explanation, we can conclude that:
angle C is congruent to angle X
angle D is congruent to angle Y
angle A is congruent to angle Z
