Please solve these 4 math equations...

1) x = 60° ; y = 70°

2) x = 50° ; y = 80°

3) x =110° ; y = 60°

4) x =60° ; y = 90°

Step-by-step explanation:

1)

We have to find the interior angle y

= 180 - 120

= 60°

Now we have to find x

=180 - (60 + 50)

= 180 - 110

= 70°

2)

We know that opposite angles are equal

So therfore y = 80°

x = 180 - 80 + 50

x = 180 - 130

x = 50°

3)

According to the figure we see that x+y=180

Exterior angle = sum of two interior angle

So, x = 50 + 60

x = 110°

Now we substitute in the x value

x + y = 180

110 + y = 180

y = 180 - 110

y = 70°

4)

Opposite angles are equal

x = 60°

The figure is a right angle triangle

So,

y =90°
