How do you solve problem with two variables

Mathematics
1 answer:
nasty-shy [4]3 years ago
4 0

Answer:


In your equations, there is only one variable you're using: y. I do not know what you mean by 2 variables, but probably you copied the wrong equations.  

......Anyways......  

To solve it, you must know that the sum of all 3 angles of a triangle is 180°.  

To set up the equation, add all three angle measures on one side of the equation, and then 180 on the other side. It should be like this:  

(6y+1)+(4y-7)+(9y+3) = 180  

Now that you're done with the set-up, I assume you know what to do next. We can't always do the work for you. ^_~  

> Add up the measures of each angle.  

> Isolate the equation with only variable on one side and only number on the other side.  

> Substitute each variable y for each angle measure and solve it.  

Hope this helps a lot. ^_^

A circle with circumference12 has an arc with a 330∘ degree central angle. What is the length of the arc?
posledela
The formula for arc length which is measured in units not degrees is \frac{ \beta }{360} *2 \pi r, where 2 pi r is the circumference.  We were given the circumference as 12 pi, so we can fill in the rest of the formula and the find the length of the arc that is intercepted by that 330° angle.  \frac{330}{360} *12 \pi gives us, after multiplying in the pi, an arc length of 34.56 units.
