Unit6: Similar Triangles

 

The ratio of the measures of the three triangles in a triangle is 10:3:7 Find the measure of the longest angle   

 

Do you mean the largest angle?  

 

Add up 10 + 3 + 7 to get 20.  Then the largest angle is (10/20) x (180^o) = 90^o  

 

The other two angles are (3/20) x (180^o) = 27^o  

                                  and (7/20) x (180^o) = 63^o
