Question

in the figure,l||m and a trans versal line t cuts them .If angle1:angle2=2:3,then find measure of all angles​

Answer 1

Answer:

Given,

L||M and T is transversal

ratio of angle 1 and angle 2 is 2:3

To prove,

measure of all angle

Proof,

Let we take x

so, angle be 2x:3x

then,

2x+3x=180° [linear pair ]

5x=180°

x=180°÷5

x=36°

now we get value of x =36°

so, 2x =2*36°=72°

3x=3*36°=108°

1=72°and 2=108°

2 =6=108° [corresponding angle1 =5=72° [corresponding angle]

1=3=72° [vertical opposite angle]

2=4=108°[vertical opposite angle]

3=7=72°[corresponding angle]

4=8=108°[corresponding angle]

hence proffed
