Question

rangle.
5. The angles of a triangle are in the ratio 3:5:4. Find the measure of each of the angles.
6. One angle of a triangle measures 30° and the other two angles are in the ratio 3:2. Find these
angles.​

Answer 1

5...3x , 4x and 5x respectively. x= 15. ➡Smallest angle in degrees is 45. ➡Greatest angle = 75 .

Answer 2

$QUESTION\\The angles of a triangle are in the ratio 3:5:4. Find the measure of each of the angles.\\ANSWER \\3x , 4x and 5x respectively.Now using the angle sum property of a triangle We have ,3x + 4X + 5x = 18012x = 180x= 180/12x= 30/2x= 15.Hence the angles are3×15=454×15= 605×15= 75➡Smallest angle in degrees is 45.➡Greatest angle = 75 .$

2ND QUESTION One angle of a triangle measures 30° and the other two angles are in the ratio 3:2. Find these

ANSWER

$The sum of all angles of a triangle is 180Let 3:2 be 3x and 2xSo ,30+3x+2x=18030+5x=1805x=180-305x=150x=150/5x=303x=3(30)902x=2(30)60$
