Question

Work out the angles marked x in each diagram you must show your working

Answer 1

Answer:

x = 125°

Step-by-step explanation:

Since ∆ ABC is a triangle the sum of it's angles add up to 180°

In order to find x we must first find $\angle$ AED

Let $\angle$ AED = E

To find $\angle$ AED add up all the angles in the triangle and equate it to 180°

That's

35 + 90 + E = 180

125 + E = 180

E = 180 - 125

E = 55°

E and x lie on a straight line

So we have

x + 55 = 180°

x = 180 - 55

x = 125°

Hope this helps you
