2^2 X 19 is the prime factorization of 76
Answer:
Step-by-step explanation:
Given,
Height of tee, H = 43 yard
Direct distance of the hole is, D = 177 yards
Now, Angle of depression of tee
Hence, angle of depression from tee to the green is
-4x+y=6
-5x-y=21
Solve for one side of either equation. I will use the first equation and solve for y.
-4x+y=6
+4x +4x
Y=4x+6
-5x-y=21
Now when you substitute, make sure to distribute properly including the easily missed negative.
-5x-(4x+6)=21
-5x-4x-6=21
-9x-6=21
-9x=27
X=27/-9
X=-3
Now that you know X, substitute to find Y.
Y=4(-3)+6
Y=-12+6
Y=-6
So your final answer is:
X=-3 Y=-6
(-3,-6)
X = length of half the base
If you draw out a triangle, the horizontal leg will be x, the vertical leg will be 147 and the angle of inclination (or angle of elevation) is 52 degrees
You'll use tangent to find x
tan(angle) = opposite/adjacent
tan(52) = 147/x
x*tan(52) = 147
x = 147/tan(52)
x = 114.84 ... this is approximate
Half the base is 114.84, so the full base is 2*114.84 = 229.68 which rounds to 230
The final answer is D.
-3
7 - 4 = 3
-3 that is the answer to the question
