Answer:
48°
Step-by-step explanation:
We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.
This means the tangent of x° = 
. Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:
Using a calculator, the answer would be:
Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.
There are two ways to do this:
Way 1- Since you know there are 4 people and each will pay 25%, you know that every person will pay equally / the same amount so you can just do 115/4 and get $28.75 per person
Way 2- You can convert 25% into a decimal by multiplying it by 100 and getting 0.25 and multiplying 0.25 x 115 to get 25% of 115, which is what everyone will pay and you get B $28.75
Answer:
First break apart 923 into 900+20+3 then do 9 times 900,9 times 20 and 9 times 3. Then add all the products together to get your answer.
Step-by-step explanation:
8x-4y=-4
4y=5+3x
8x(5+3x) =-4
X= 1/5
4y=5+3 x 1/5
Y=7/5
X=1/5 Y=7/5
