Question

Pls help T-T I really need help

Answer 1

10.3 units

Explanation:

Base of the right angle triangle:

5/2 = 2.5

CE² = 2.5² + 10²

CE² = 106.25

CE = 10.30776406

Answer 2

10.3

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
