No you got the wrong answer the answer is 256 pi.
Answer:
The speed of the faster plane is 899 km/hr
The speed of the slower plane is 824 km/hr
Step-by-step explanation:
Equation for faster plane:
(1) +d+=+s%2A4+
Equation for slower plane:
(2) +6892+-+d+=+%28+s+-+75+%29%2A4+
Both side multiply by one number.
The answer is 120 degrees I hope this helps
The process used in the picture is cross multiplying. Make an x through the numbers and multiply them by each other. That's why 21 was multiplied by 14 and 49 was multiplied by n. The value of n is unknown, so it simplifies to 49n, and 14*21=21.4. So basically to recap, make an x, multiply the terms that are diagonal from each other, write both of the answers next to each other, and put an = sign in between them. If you don't understand I can try to explain differently ☺
