Vertical angles are equal
5x - 40 = 3x + 8
5x - 3x = 8 + 40
2x = 48
x = 48/2
x = 24
m∠ABC = 3x + 8 = 3 * 24 + 8 = 80°
(or m∠ABC = 5x - 40 = 5 * 24 - 40 = 80°)
Answer:
<h2>y - 6 = 2(x - 7)</h2>
Step-by-step explanation:
The point-slope of an equation of a line:

m - slope
The formula of a slope:

We have the poinys (-1, -10) and (5, 2). Substitute:

Put the value of the slope and the coordinateso f the point (5, 2), to the equation of a line:

In the question we have y - 6 = ...
Therefore
<em>subtract 4 from both sides</em>
<em>use the distributive property</em>

<em>distributive</em>

Step-by-step explanation:
the slope is 5 I think it is 5
Given that ABC is a right triangle.
The length of AC = 10 and AB = 17
We need to determine the m∠B
<u>The measure of ∠B:</u>
The side opposite to ∠B is AC and the hypotenuse of the triangle is AB
The m∠B can be determined using the trigonometric identity,

where
and 
Substituting, we get;

Substituting the values, we get;


Taking
on both sides of the equation, we have;


Rounding off to the nearest tenth, we get;

Hence, the measure of ∠B is 36.0°
