Question

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the 3rd angle is 68 degrees more than the measure of the 2nd angle. Use the fact that the sum of the measures of the 3 angles of a triangle is 180 degrees to find the measure of each angle. The measure of the smallest angle is??

Answer 1

Let us assume the scond angle to be x.
Then first angle=2x
Third angle=x+68
x+2x+x+68=180
Can u find x nw?

Answer 2

ok so im going to combine like terms right?

Answer 3

ya. that's the first step.

Answer 4

ok so i get 4x+68=180. so now i subtract 68 from both sides?

Answer 5

ya

Answer 6

then i get 4x=112 so i divide by 4 on both sides and get 28? After that how do i find the measure of the smallest angle?

Answer 7

ya

Answer 8

Ok so how do i find the measure of the smallest angle?

Answer 9

The value of x is the measure of small angle.

Answer 10

so 28 is the measure of the smallest angle?

Answer 11

ya.:)

Answer 12

what would the measure of the 2nd largest angle be?

Answer 13

2x

Answer 14

that's not right it said.

Answer 15

It says what would the measure of the 2nd largest angle be?

Answer 16

2x=?

Answer 17

what do i multiply there where that x is ?

Answer 18

would i do 2(28)?

Answer 19

yes

Answer 20

and how would i find the measure of the largest angle?

Answer 21

x+68=?

Answer 22

so 28+68?

Answer 23

so would the largest angle be 96?

Answer 24

yes

Answer 25

If i post another one kind of similar will u help me on it? you are great

Answer 26

ya sure. post it.
