Question

In a triangle, the second angle is twice the measure of the first, and the third angle is three times the measure of the second. Find the measure of the third angle.

Answer 1

ok... let suppose...

the first angle = x
the second angle = y
the third angle = z

now according to the statement of the question... it will be like this... x+2y+3z=180 degrees

ratio of the angles here will be 1:2:3 = 6...

so to find the third angle... 3/6*180 = 90 degrees....

Answer 2

ok... do this short procedure... ratio of that side whom you want to find/whole ratio summation*total angle.... now got it.... @ltp1212

Answer 3

dear follow the ratios and solve all....
