I don’t remember what formula this is called but the formula says that all angles in a triangle should add up to 180, so 75+37= 112, 180-112= 68
Answer:
a. 68
Step-by-step explanation:
You just have to subtract these two numbers from 180 because adding all the angles of a triangle the resulta is 180. Subtracting those numbers from 180 will give you the result.

Find the Slope between two points: (-1,9) and (2, 3)
Answers
Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = y2 - y1
x2 - x1
3 - 9 = -6
2 -(-1) = 3
= -2
The slope between the two points is -2.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The slope is given as,
m = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
Now,
(-1, 9) = (a, b) and (2, 3) = (c, d)
m = (3 - 9) / (2 + 1)
m = -6 / 3
m = -2
Thus,
The slope is -2.

If the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that the equations are,
y=3x+14 ----------(1)
y= -4x -------------(2)
In order to solve "by substitution," you must first solve one of the equations for one of the variables (you choose which one), plug that solution back into the other equation, "substituting" for the selected variable and then solve for the other.
Substitute the value of y from equation 2 in equation 1 as
y=3x+14
-4x=3x+14
Rearrange the equation in order to find the value of x as
-4x-3x=14
-7x=14
x= -14/7
x= -2
Put the value of x in equation 2 as
y= -4x
y= -4(-2)
y=8
Thus, if the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.

Answer:
The answer is:
B) 66 degrees
Step-by-step explanation:
Since the triangle is an isosceles triangle, angle C is the same as angle B.
57 + 57 = 114
Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...
180 - 114 = 66
Angle A must equal 66 degrees for the triangle to equal 180 degrees.

Answers
Answer:
its D. (3,0)
Step-by-step explanation:
The ordered pair makes both inequalities true is (3,0) if the inequalities are y > –2x + 3, and y < x – 2.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The inequalities are:
y > –2x + 3
y < x – 2
Plug the point in the above inequality:
(3,0)
The above point satisfy the inequality.
Thus, the ordered pair makes both inequalities true is (3,0) if the inequalities are y > –2x + 3, and y < x – 2.

So, the line is parallel to - 3x - 4y = 5 and the line passes through the point (4, -2).
So, what I did was I pulled up a graphing site on my Chromebook called DESMOS, maybe you could use this in the future to help you out a little bit.
I then graphed the line of - 3x - 4y = 5 or you could simplify it to y = -3/4x + 5/4 .
The slope of the line is 3/4 . You can find this by taking the points (-15, 10) and (5, -5) and doing this...
m = y2 - y1 divided by x2 - x1 which would look like -5 - 10 divided by 5 - -15 which would simplify to -15 over 20 which would get you a slope of -3/4.
Then you take the formula y - y1 = m( x - x1) and substitute in your variables.
It should look something like this y + 2 = - 3/4 ( x - 4) .
This answer is parallel to -3x - 4y = 5.
I’m sorry, I’m not very good at explaining, but I hope this helps you out.
