X = 60°
To work this out, you would do 50°+70° to get 120°. You would then subtract this from 180° (the total for any triangle) to get the final answer of 60°.
Answer:
I got 0.3428571429
Step-by-step explanation:
I got it by inputting (2/5)*(6/7) into my calculator, but if you need more let me know
Its true because integers are negative and positive numbers including zero, and a whole number is a positive counting number including zero
Looks like the function on the right hand side is

We can write it in terms of the Heaviside function,

as

Now for the ODE: take the Laplace transform of both sides:


Solve for <em>Y</em>(<em>s</em>), then take the inverse transform to solve for <em>y</em>(<em>t</em>):
