Question

Will give medals.
If the angles of a triangle with measures in the ratio of 5:6:7, the find the measure of the smallest angle.

a. 40 degrees
b. 50 degrees
c. 60 degrees
d. 70 degrees

Answer 1

Let angles be 5x, 6x and 7x

Now we know that sum of angles in a triangle is 180 degrees.

therefore
5x+ 6x + 7x = 180

You can solve it now.

Answer 2

But I found the answer already.

If someone will check it for me, you can have the medal :)

For others:

Add the numbers
5 + 6 + 7 = 18

18 will be the denominator.

5/18
6/18
7/18

Multiply these fractions by 180 since all triangles = 180.

5/18 x 180 = 50
6/18 x 180 = 60
7/18 x 180 = 70

These are our angle degrees. 50 is the smallest.
