The measure of each angle in the triangle

Mathematics
1 answer:
telo118 [61]2 years ago

M of A = x
m of B = 2x-7
m of C = 2x+2

By the angle sum property of a triangle, we know that all the angles of a triangle add up to 180 degrees.

Thus we can create a linear equation

x + 2x-7 + 2x+2 = 180
4x = 185
x = 185/4
x = 46.25

Thus
m of A = 46.25
m of B = 2(46.25) -7 = 85.5
m of C = 2(46.25) +2 = 90.5

A test is worth 80 points. Multiple-choice questions are worth 2 points, and
gavmur [86]

Answer:

<u>There are 10 multiple-choice questions and 15 short-answer questions in the test</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Test worth 80 points

Multiple-choice questions are worth 2 points

Short-answer questions are worth 4 points

Multiple-choice questions + Short-answer questions = 25

2. How  many multiple-choice questions are there?

Let's solve this problem, this way:

m = Multiple-choice questions

s = Short-answer questions

Our equations system is:

m + s = 25

2m + 4s = 80

Solving for m in the 1st equation:

m + s = 25

m = 25 - s

Substituting m in the 2nd equation and solving for s:

2m + 4s = 80

2 * ( 25 - s) + 4s = 80

50 - 2s + 4s = 80

2s = 80 - 50

2s = 30

<u>s = 30/2 = 15</u>

Substituting s in the 1st equation and solving for m:

m = 25 - 15

<u>m = 10 </u>

<u>There are 10 multiple-choice questions and 15 short-answer questions in the test</u>

Type the correct answer in the box. Use numerals instead of words.
Pani-rosa [81]

Answer:

Step-by-step explanation:

7- \sqrt[3]{2-x} =12

we have to just keep in mind to do the same operation to both sides of the equal sign

7-7- \sqrt[3]{2-x} =12-7 ; subtract 7 from both sides

- \sqrt[3]{2-x} = 5 ; multiply both sides by -1

\sqrt[3]{2-x} = -5 ; raise both sides to the power 3

2-x = (-5)³

2-x = -125 ; subtract 2 from both sides

-x = -125-2

-x =-127; multiply both sides by -1

x= 127

Based on the graph, what is the initial value of the linear relationship?
alex41 [277]

Answer: two over three

Step-by-step explanation:

y=ax+b

line intercepts y at (0,-2)

Therefore, y=ax-2

Substitute x = 3 in y =ax-2

y=3a-2

To find the x-intercept, y = 0

3a-2=0\\3a=2\\a=\frac{2}{3}

The slope is 2/3

y-intercept is -2

So two over three
