Answer 1

Answer:

55+90+x=180

145+x=180

x=180-145

x=35

I hope it helps you

Answer 2

Answer:

x = 35°

Step-by-step explanation:

We can solve for x by using angle sum property of a triangle

In the first triangle angle1 + angle2 + angle3 = 180°

 = 55° + x + angle3 = 180°

Angle 3 = 90° because the angle left to it is also 90°. We can prove this with angle sum property on a straight line.

So lets continue with the equation,

 = 55° + x + 90° = 180°

 => x = 180° - (55° + 90°)

 => x = (180° - 145°) or 35°
