pls help T-T I really need help

Answer:
10.3
Step-by-step explanation:
CD is 5 units long
We need 1/2 of the length of 2.5 units
The slant height is 10 units
We want to find CE
We can use the Pythagorean theorem
a^2 + b^2 = c^2
2.5^2 + 10^2 = CE^2
6.25 + 100 = CE^2
106.25 = CE^2
Take the square root of each side
10.30776406 = CE
To the nearest tenth
10.3
Answer:
10.3 units
Step-by-step explanation:
Base of the right angle triangle:
5/2 = 2.5
CE² = 2.5² + 10²
CE² = 106.25
CE = 10.30776406
