Answer:
B. A triangle can have only 1 right angle.
Step-by-step explanation:
Think of a right angle as an L. If you have an L connecting to a backwards L, you have an open shape. Triangles have 3 sides and are closed shapes. If a triangle has two right angles, you could connect the two ends but that would give you a square or triangle.
Hope this helped!
Step-by-step explanation:
if I understand you correctly, then
cos(theta) = -0.7
then Theta = 134.427004...°
and that is rounded 134.43°

We are given function: f(x) = 12x+3.
Generally we start x from 0 and we can take any number for x to get some real number of f(x).
Therefore, domain of the function start from 0.
And we can take any number 0 or greater than 0 to get some value of f(x).
So, we can say that domain of the function is " All real numbers greater than or equal to 0".
<h3>Therefore, Prectical domain : All real numbers greater than or equal to 0.</h3>
