2√x−3√xyx+√y is your answer.
Answer:
55 degrees
Step-by-step explanation:
A complementary angle equals 90 degrees so you know that the two angles together must equal that. The easiest way to set up these problems are to turn it into an algebraic equation. You know that angle a is 20 more than angle b, or angle a is (x+20) and angle b is (x). Your equation would read: x+x+20=90. Simply solve this equation then plug in the answer to whichever angle you need. 2x+20=90, 2x=70, x=35. Angle A is 20 degrees longer making it equal 55.
Since the line is parallel to 2x + 3y = 4, it means that it have the same gradient.
2x + 3y = 4
3y = 4 - 2x
So the gradient =
The equation of the line that is parallel to 2x + 3y = 4,
Ans: 3y = - 2x - 10
