Question

ii.
If the angles of a triangle are in the ratio 4:5:9, find the measures of the angles of the
triangle and name the type of triangle.
[5x2=10]​

Answer 1

Answer:

Step-by-step explanation: LET THE ANGLES BE 4x,5x,9x

4x+5x+9x=180 (ANGLE SUM PROPERTY)

18x=180

x=180/18=10 degrees

ANGLE 1= 4 x 10 = 40 DEGREE

ANGLE 2=5 x 10 = 50 DEGREE

ANGLE 3 = 9 x 10= 90 DEGREE

IT IS A RIGHT ANGLED TRIANGLE AS ONE ANGLE=90 DEGREE

Answer 2

Answer:

The angles of a triangle are in the ratio is 4 :5 :9

the total of triangle = 180°

the total of triangle are in the ratio is 4 +5+9 = 18

the measure ment of the angles of the triangle are

• 180° × 4/18

= 10° × 4

= 40°

• 180° × 5/18

= 10° × 5

= 50°

• 180° × 9/18

= 10° × 9

= 90°

the name of the triangle is scalene triangle.
