OK so to solve this we will subtract 16x from 2x to get -14x
-14x - 4y + 3x^2 + 7y
add - 4y and 7y to get 3y
-14x + 3x^2 +3y
and then to simplify we are going to move the -14x
3x^2 +3y - 14x
Angle between 16 and 18 = 90 + 55 = 145°

Answer:
5√2
Step-by-step explanation:
This triangle is a 45 - 45- -90 triangle which is a special trig triangle. This triangle has side lengths which are always the lengths or a a multiple of 1 - 1 - √2.
Since the side length which is longest is 10, this corresponds to the side length √2. Look for a number which when multiplied with √2 gives 10.
√2*√50 = √100 = 10.
The triangle has scaled up the parent triangle by a factor of √50. This means the other sides are 1*√50 = √50 = 5√2
This simplifies to 5√2 since √50 = √25*√2 = 5√2.
