Answer:
Step-by-step explanation:
CABD is half-circle as CD is diameter and cuts the circle in half
- CABD = CA + AB + BD
- 180° = x + 70° + x
- 110° = 2x
- x = 110°/2
- x = 55°
Correct choice is d)
Answer: 153.86
Step-by-step explanation: Area is equal to PI R^2 so if 7 is the radius then the answer is
To compute for your profit, you just have to deduct your
operating expenses to your gross margin. The gross margin is already the gross
profit you have earned which is computed by deducting cost of goods sold to the
revenue.
23,487 (gross margin) – 8,123 (operating expenses) = 15,364
(profit)
Answer:
The answer would be 3

This is because, hope this makes sense, Shes 8 years older and the answer choices were: 3, 4, 11 and 12, well 3+8=11 and it says next year she will be 3 times his age, still being 8 years older, next year lance will be 4 and whats 3 years times 4, twelve. And whats 8 years older than four 12. Hope this makes sense but it has to be 3.
Answer:
Step-by-step explanation:
<u>Heron's Area formula:</u>
- A =
, where s is semi-perimeter - s = 1/2(a + b + c)
We are given two sides and the included angle.
<u>Use the law of cosines to find the missing side:</u>
- a² = b² + c² - 2bccos A
- a² = 77² + 41² - 2*77*41*cos 79
- a² = 6405
- a = 80 (rounded)
<u>Now find the value of s:</u>
- s = 1/2(80 + 77 + 41) = 99
<u>Find the area:</u>
- A =
= 
= 1549.24
