Hello,
tan C=AB/BC==>BC=tan 49° * 250=287,59210... (feet)
sin C=AB/AC==>AC=250/sin 49°=331,253248... (feet)
Answer:
CB = sqrt62
Step-by-step explanation:
The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2 = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so 4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62
Sorry if this isn't exactly right, there's no exact way to find DB.
140.4 since the sides are equal . Iguess . I did not calculate or anything but mentally
2/12 or 1/6.
