Answer:
150˚ or 330˚
Step-by-step explanation:
It is easier to use the calculator, but you can use the unit circle too.
Calculator:
Plug in the equation without the negative, and you get 30˚ which is your reference angle. But since tangent is negative, the angle is in either the second quadrant, or the fourth (because tangent is negative in these quadrants). Now using your reference angle, you can find the answer.
X + y = 20 Substitute
x by 2 y - 4 in x + y = 20 to obtain 2 y •
4 + y = 20 Solve for y to find y = 8 and
x = 2y - 4 = 12
This is a guess using logic, but my answer for this is that she concluded that she walked faster in the first 15 minutes. An increase in speed would increase the distance she walked in that amount of time
Hey there! Since these shows you must find the graph so finally the answers should be
1.The slope of 1/5
2.The slope of DC =2/3
3.The slope of AB= 1/4
4.The slope of DA=7/2
5. B. Yes the quadrilateral has two pairs of of opposites that are perpendicular and all of its interior angles are right angles.
Hope this helped.
