Question

Please help!

I attempted this question myself (second attachment) but got the answer wrong, can someone help me identify where I failed? Was it simply a calculation slip-up or an actual fault in how I tackled the question?

Answer 1

Explanation:

The issue with your answer is that on line AD, you forgot to account for the left triangle when adding 10 cm + 14 cm = 24 cm. To answer this question, I would recommend solving for the AB triangle with 7.5 cm and 6 cm (using pythagorean theorem). Afterwards, you can use that answer, add it to the length of BC and subtract both from AD (24 cm) to solve for MD. Then, you can solve for the angle. Hope that helps.
