Complementary angles add up to 90 so
angle + 47 = 90
angle = 90 - 47
angle = 43 so A
move all terms to the left side and set equals to zero. then set each factor equal to zero
In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:
sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
-4 < x < 6 is ur compound inequality
Y=2x is the equation that is //
