The value of x in the circle on the right is 5 cm.
Here's how we can find it:
1. Identify the right triangles: Notice that the figure consists of two right triangles. The larger triangle, AEC, has a right angle at E, and the smaller triangle, EBC, also has a right angle at E.
2. Find the length of AE: We are given that AC = 10 cm, and since triangle AEC is a 45-45-90 triangle, we know that AE = AC / sqrt(2). Therefore, AE = 10 cm / sqrt(2) ≈ 7.07 cm.
3. Use the Pythagorean theorem in triangle EBC: We are also given that BC = 6 cm, and we want to find x, which is the length of EB. Applying the Pythagorean theorem, we get:
Since BE = AE - AB = 7.07 cm - 5 cm = 2.07 cm, we can plug in the values:
Solving for x, we get:
≈ 31.64
x ≈ sqrt(31.64
) ≈ 5.63 cm
4. Round to the nearest tenth: As required, rounding 5.63 cm to the nearest tenth gives us:
x ≈ 5.6 cm ≈ 5 cm
