Question

1. Two lines cross each other. The sum of two
opposite angles is 60°. Find the measures
of all the angles.
2. The measures of the angles when two lines
cross each other are 2aº, aº, 2aº and aº.
Find the measures of each angle.​

Answer 1

Answer:

angles are60,30,60,30.....

Answer 2

Answer:

Hi friend here's your answer.

Step-by-step explanation:

1. Let one opposite angle be x.

Since the opposite angles are equal, the other angle is also x.

Therefore 2x = 60 degrees

or, x = 30 degrees.

Therefore, the opposite angles are 30 and 30 degrees.

Now, the adjacent angles are:

180-30 = 50 degrees.

Since they are also opposite angles, the remaining angle is also 50 degrees.

So the angles are 30, 50, 30 and 50 degrees.

2. 2a + 2a + a + a = 360 degrees.

6a = 360

a = 60 degrees.

Therefore angles are 120, 60, 120, 60 degrees.

Hope you'll understand it.
