ASAP pls help me with this
Answer:
x = 20
Step-by-step explanation:
If A || B, then ∠2 should equal to ∠3 (Alternate angles).
3x - 10 = x + 30
Isolate like terms.
3x - x = 30 + 10
Evaluate like terms.
2x = 40
Find x.
x = 40 ÷ 2
x = 20
Answer:
x = 20.
Angles 2 and 3 are measured as 50 degrees.
Step-by-step explanation:
Angles 2 and 3 are congruent, meaning that they are equal.
Set the two equations equal to each other and solve for x.
3x-10=x+30 (subtract x from the left side and add 10 to the right. This gets the x's and the plain numbers on the same side of the equation)
2x=40 (Divide by 2)
x = 20
Check your work by plugging in 20 for x in each expression. If the two expressions are equal when you do so, then you know you've worked out the problem correctly.
Angle 2:
3(20)-10
60 - 10 = 50
Angle 3:
20 + 30 = 50
Both expressions equal 50 when plugging in 20 for x, so this is the correct answer.

The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
largest angle?
Answer:
84°
Step-by-step explanation:
Let the measures of the triangle be 5x, 7x, 3x.
By interior angle sum postulate of a triangle.
5x + 7x + 3x = 180°
15x = 180°
x = 180°/15
x = 12°
7x = 7*12°= 84°
Measure of the largest angle = 84°

Find the slope of the line. Enter your answer as
a number, fraction, or undefined. Reduce to
lowest terms where necessary.
Answer:
m = undefined
General Formulas and Concepts:
Algebra I
Vertical Line Test - Tells us if a graph is a functionVertical Lines - slopes are undefinedStep-by-step explanation:
If the slope m was equal to 0, then it would be a horizontal line rather than a vertical line.
Using the Vertical Line Test, we also know that the graph is not a function.
Usually a vertical line has an undefined slope, as x equals a certain number, and m = unknown.
Answer: It's undefined, because it's vertical
Charlie bought 2 3/4 pounds of pears for $0.76 per pound and 2 3/4 pounds of grapes for $1.40 per pound. How much money in dollars and cents did charlie pay for the pears and grapes.
Answer
Charlie paid $5.94
Step-by-step explanation:
0.76x2 3/4=2.09
1.40x2.75=3.85
3.85+2.09=$5.94
The points (-2, 4) and (1,r) lie on a line with slope 3. Find the missing coordinate r.
Answer:
-9
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
(r - 11)/(4 - (-1)) = (r - 11)/5
So, (r - 11)/5 = -4
r - 11 = -20
r = -9

Determine which of the following angle measures are correct. Select all that apply.
OmZBAC = 72°
O
m2BCD = 68°
Om ACB = 112°
m2ABC = 68°
mzBCD=108°
*see attachment for diagram
Answer:
✔️m<BAC = 72°
✔️m<BCD = 108°
Step-by-step explanation:
Given:
m<ABC = (4x - 16)°
m<ACB = (5x + 7)°
Find the numerical value of m<ABC, m<ACB, m<BAC, and m<BCD.
First we need to determine the value of x.
The ∆ given is an isosceles triangle with two equal sides, therefore, the angles opposite the two equal sides would also be equal.
Therefore:
(4x - 16)° + 2(5x + 7)° = 180° (sum of ∆)
Solve for x
4x - 16 + 10x + 14 = 180
Add like terms
14x - 2 = 180
Add 2 to both sides
14x = 182
Divide both sides by 14
x = 13
Find the measure of each angle by plugging in the value of x where necessary:
✔️m<ABC = (4x - 16)° = 4(13) - 16
m<ABC = 36°
✔️m<ACB = (5x + 7)° = 5(13) + 7
m<ACB = 72°
✔️m<BAC = m<ACB (both are base angles of the isosceles ∆, so they are equal)
Therefore,
m<BAC = 72°
✔️m<BCD = m<ABC + m<ACB (exterior angle theorem of a triangle)
m<BCD = 36 + 72 (Substitution)
m<BCD = 108°
Therefore, the angle measures that are correct are:
✔️m<BAC = 72°
✔️m<BCD = 108°
A man left his waiter a $10 tip that was 20% of his bill. How much was the man's bill?
Answer:
50
Step-by-step explanation:
Answer:
The bills total was 50$
Step-by-step explanation:
So 20% is equal to 10 dollars.In order to find out the total you need to reach 100% so 5 mulitplied by 20 is 100 so 10 multiplied by 5 is 50 therefore the bill was 50.
