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 [tex]\angle[/tex] AED
Let [tex]\angle[/tex] AED = E
To find [tex]\angle[/tex] 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
