Put them all in an equation where (m<1)+(m<2)+(m<3)=180 because all the angles of a triangle added together equals 180. From there, solve for x using algebra. Combine like terms and then isolate x. For the second part, use the value you found for x and find the measurement of angle 3. angle 4 is supplemental to angle 3 because angle 3 plus angle 4 is equal to 180 degrees. subtract the measurement of angle 3 from 180 to find angle 4. let me know if you have any trouble. i will find a computer to better explain if needed. im using a mobile phone, so communication is a bit limited

What is the answer to 2a + 3b =
Rainbow [258]

Answer:

2a+3b

Step-by-step explanation:

There wouldn't be a simplfied answer or solution if you don't have a solution for either a or b or both. And they are not like terms, so you can't add them together.

So the answer is 2a + 3b.

I hope this helps!

Have a great day!
