Answer 1

10

Answer 2

The sum of the angle measures of a triangle is 180.

m<A + m<B + m<C = 180

Substituting,

4x + 3x + 1 + 7x +11 = 180

Solve this ^^ for x.

Answer 3

What is 4x + 3x + 7x = ?

Answer 4

@DeeBush96 ^^^

Answer 5

14x + 12=180

Answer 6

@Directrix what i do with the 12

Answer 7

14x + 12=180
-12 -12 ---->Subtract 12 from both sides
-----------------

Answer 8

14 x = ?

x = ?

Answer 9

14

Answer 10

12 i meant

Answer 11

Okay

Answer 12

x = 12

Now, we have to get the actual measures of the angles of the triangle.

4x = 4*12 = ?

3x + 1 = 3*12 + 1 = ?

7x +11 = 7*12 + 11 = ?

Answer 13

95

Answer 14

There are three angles. 95 is the last one. You have two others to do. Look back.

Answer 15

what letter is 95

Answer 16

@dir

Answer 17

m<C= 7x +11 = 7*12 + 11 = 95 --> That is the one you have done so far.

Answer 18

m<A= 4x = 4*12 = ?

Answer 19

It is too early to choose options. We have another theorem to apply after you get these angle measures cranked out.

Answer 20

4 times 12 equals ?

Answer 21

88

Answer 22

Try again.

Answer 23

48

Answer 24

sorry i typed it wrong lol

Answer 25

Now, for angle B

3x + 1 = 3*12 + 1 = ?

Answer 26

37

Answer 27

Here are the angles on the triangle.

Coming next is the theorem we need.

Answer 29

The smallest side of the triangle is the side opposite the smallest angle.

37 is the smallest angle (<B).

Which side is opposite <B ?----> @DeeBush96

Answer 30

48

Answer 31

48 is an angle.

What side of the triangle is opposite angle B.

The answer is AB, BC, or AC

Answer 32

Look at this diagram.

Answer 33

What is the name of the side outlined in red?
