Question

solve it ......plzzz​

Answer 1

Answer:

Let us add the 1 and 2 angles, so we get,

x+30+2x+15=180°

(because the diagram forms a quadrilateral in which sum of angle1 and angle 2 give 180°)

So, 3x+45=180

3x=135

x=45°

So, angle 1 = angle 3 = 75°

(Because in this quadrilateral opposite angles are equal)

And,

Angle 2 = angle 4 = 105°

(Because opposite angles are equal in this quadrilateral)

Hence,

Angle 3=75°

And,. Angle 4=105°

Verifying:-

Angle1 + angle2 + angle3+ angle4

= 360°

(Sum of all angles in a quadrilateral gives 360°)

So,

75°+105°+75°+105°=360°

360°=360°

Answer 2

Answer:

a/q..

angle_1+2will be 180°

(x+30°)+(2x+15°)=180

3x+45=180

3x=180-45

x=135/3

x=45

then-angle1 =x+30 which is75°

it is also equal to angle-3

and angle2=2x+15 which is 105°

then angle4 will also be 105°

vertically opposite angle....

i hope it's sufficient explanation.
