Geometry ! for this figure, what is the value of x? explain the steps taken to get the answer!

So what I did was:

Found all the angles in a triangle
Vertically opposite angles are equal so in the middle triangle two of the angles are 96° and 42°
Find the last angle
180-(96+42)=180-138=42°

To find x
By using the parallel lines with 1 arrow we can use alternate interior angles to find x
So...

x=42°

Sorry it’s kinda confusing, there’s other ways to work it out as well, if you don’t understand feel free to let me know and I can try to explain a different way to solve

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
