The measure of angle 3 from the figure is 110 degrees

<h3>Lines and angles</h3>

An angle is the intersection between two lines. From the given figure, we have the following parameters

m∠1= 40°,

m∠2= 70°.

Required

Measure of angle 3

The sum of the interior angles of the triangle is equal to the exterior

Sum of interior = <1 + <2

Sum of interior = 40 + 70

Sum of interior =110 degrees

Hence the measure of angle 3 from the figure is 110 degrees

What is the solution to the system graphed below?
Feliz [49]

Answer:

Option D.

Step-by-step explanation:

We need to find the solution to the system graphed below.

If a system of equation have 2 linear equation then the intersection point of both lines lines is the solution of the system of equations.

In the given graph two straight lines intersect each other at (-1,-1).

Point of intersection = (-1,-1)

So, by using the given graph we can conclude that the solution of given system of equations is (-1,-1).

Therefore, the correct option is D.

Solve the formula for one of its variables using addition subtraction and/ or division
Sati [7]

One way of doing this would be to look at the πr² as if it were a single term. Then we could divide both sides by πr², which leaves h = V/πr².

Solve the system and enter the smallest x-coordinate first
ankoles [38]
Answer:
(2,-3)(6,5)
Step-by-step explanation:
We can use substitution to get the equation: x^2-6x+5 = 2x-7
Solve:
x^2-6x+5 = 2x-7
x^2 = 8x-12
x^2-8x+12 = 0 (we now have a polynomial)
(x-6)(x-2) = 0 (set each equation to equal 0 and solve)
x-6 = 0 --> x=6
x-2 = 0 --> x=2
To get the Y coordinates:
y=2(2)-7 --> y = -3
y = 2(6)-7 --> y = 5

Check work:
5 = 6^2-6(6)+5 --> 5 = 36-36 +5 --> 5=5
-3 = 2^2-6(2)+5 --> -3 = 4-12+5 --> -3=-3
