Answer:
Step-by-step explanation:
You can simplify this by collecting the like terms. The only like terms are the pair 2x and 18 x
2x-18x = -16x
Now, put them back together,
-16x + 14y-19
I don’t remember how to do a and b but A is 39
You do it be dividing the numerator and denominator by the same number, but you have to make sure the divide into whole numbers
Answer:
It is 40 degrees.
Step-by-step explanation:
You can start off by understanding this is not a right angle (exactly 90 degrees, think of a corner of a room) or and obtuse angle (more than 90 degrees, bigger than a right angle). With that information we know that it is an acute angle (less than 90 degrees, smaller than a right angle). With that we have 40 and 50 degrees left. When you compare the angle with the 40 degrees one, it is the same size. The angle 1 is a reflection of the triangle with the 40 degrees angle. Hope this helps :)
