ANSWER ASAP! MARK BRAINLIEST

Mathematics
1 answer:
patriot [66]3 years ago
4 0

Answer:

So If you start with sinØ = .5

your calculator is programmed to always give the closest angle to 0, and that would be 30°

You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.

Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems

notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102

I would have found angle S first, the largest angle always opposite the largest side.

7^2 = 5^2 + 4^2 - 2(5)(4)cosØ

40cosØ = -8

cosØ = -8/40 = -1/5

Ø = 101.537°

Now you can use the sine law and you will find the correct other angles.

Ulleksa [173]

Answer:

A. Equation is c=25+15.75x

B. Cost is $88


Step-by-step explanation:

A)

Suppose you rent for x hours and each hour costs $15.75

<u><em>How much would you need to pay?</em></u>

15.75x

Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay 25+15.75x

This is the equation of renting a snowboard for x hours.

Equation is c=25+15.75x

  • Where x is the number of hours you rent the snowboard, and
  • c is the total cost

B)

If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.

To know how much it will cost, you simply plug in 4 into x (in the equation):

c=25+15.75x\\c=25+15.75(4)\\c=88

Cost is $88
