Question

Pls solve this problem guys

Answer 1

Here, it's given that
$x - y = 70$
And, we know that
$x + y = 180 \: \: \: \: \: (linear \: pair \: property)$
Now,
Adding both equations, we get

$(x - y) + (x + y) = 180 + 70$
$(x - y + x + y) = 250$
$2x = 250$
$x = \frac{250}{2}$
$x = 125$
So, x = 125

Now, assigning the value of x in equation 1, we get

$x - y = 70$
$125 - y = 70$
$y = 125 - 70$
$y = 55$


Therefore we get the answer

x = 125
y = 55

Hope it'll help.

Answer 2

here x-y=70°
also x+y= 90°
so adding both,
2x=160°
x=80°
hence x-y=70°
x+y=180
subtracting
-2y= -110
y=55
hence y= 80+55
y=135°
