Question

TRIANGLE HELP!!!!!!!!

Answer 1

You see the small green marks on 2 of the triangle's angles?

Answer 2

yes

Answer 3

Do you know what they mean?

Answer 4

no @mathstudent55

Answer 5

They mean that the two angles are congruent.

Answer 6

What is the sum of the measures of the angles of a triangle?

Answer 7

105 degrees

Answer 8

360 degrees. You know the measure of one angle, 105. So that means that the two other angles are all that is left. Since they are the same, you can divide by two.

Answer 9

75 degrees @austinL

Answer 10

The sum of the measures of the angles of a triangle is 180 degrees.
One angle has measure 105 degrees.
That leaves 180 - 105 = 75
The other two angles have a combined nmeasure of 75 degrees.

Answer 11

That means eaxh of the other two angles measures 75/2

Answer 12

Sorry, silly error :$

Answer 13

75/2=36 @mathstudent55

Answer 14

Can i get help on the next question

Answer 15

That is incorrect.

Answer 16

72/2 = 36
Here it's 75/2, so it's not 36.

Answer 17

37.5 is the asnwer

Answer 18

right

Answer 19

how do i solve the next question

Answer 20

What is the sum of the measures of the angles of a triangle?

Answer 21

This is for the next question.

Answer 22

180 right ? @mathstudent55

Answer 23

Yes.
What are the measures of the three angles of the triangle?

Answer 24

60 @mathstudent55

Answer 25

Did you look a the drawing? Where do you see an angle that measures 60? I see one that measures 32 degrees. What do the other two angles measure?

Answer 26

i am getting negative numbers

Answer 27

Are we solving the same problem?

Answer 28

Is this the problem?

Answer 29

yes @mathstudent55

Answer 30

Ok. Let's start again.
The sum of the measures of the angles of a triangle is 180 degrees.
Ok so far?

Answer 31

yes

Answer 32

Now look at the triangle. It has angles A, B, and C.
Each angle has a measure written.
Can you tell me what the three angle measures are?

Answer 33

how can i set it up ?

Answer 34

The angles have measures: 32, 11x - 9, and 4x + 7
Now you need to add them and set the sum equal to zero.
32 + 11x - 9 + 4x + 7 = 180
Solve the equation for x.
30 + 15x = 180
15x = 150
x = 10

m<ABC = 11x - 9
Now we plug in 10 for x:
m<ABC = 11(10) - 9
m<ABC = 101 degrees
