Answer:
A. 19.3ft B. 5.2ft
Step-by-step explanation:
So the ladder leaning against the wall forms a triangle. The hypotenuse of
triangle is the ladder (20) and the angle given between ladder an ground is 75 degrees. Use trig to find the height of the wall which is the leg of the triangle.
Sine of Angle is opposite side/hypotenuse
Cosine of Angle is adjacent side/hypotenuse
so Sine of 75 degrees = Wall height/20
Wall height = 20 times Sine of 75 degrees
Sine of 75 degrees = .9659
20 times (.9659) = 19.3ft
So now use Cosine to find the other leg of the triangle (the distance between the bottom of ladder to the wall)
Cosine of 75 degrees = Distance wall to base of ladder / 20
Cosine of 75 degrees = .2588
20 times (.2588) = 5.2ft
Answer:

Step-by-step explanation:
B is the correct answer
The exponent means how many times your multiplying the number to the power of set exponent
So 6^3 is 6x6x6
Answer:
There are 1440 minutes in one day.
You need to get the ‘A’ on one side and the numbers on another. So add 4a to the left side which is -3a-11 < 1. Then you add 11 to the right side. So -3a< 12. To get a alone divide it by -3 on both sides. Also, when you divide a negative number the sign gets switched to the the other side so your answer is:
a > -4
