This is simple, what is the total degree of a triangle? 180
so add up 70 + 30 is 100, the answer to x is 80
Answer:
x = 13
Step-by-step explanation:
y=50
50 = 5x - 15
50 + 15 = 5x
65 = 5x
65/5 = 5x/5
13 = x
We have a circle of radius 5 m inside a square of side 10 m. The shaded area is:

Now, we calculate the area of the square and the circle:

Finally, the shaded area is:
