The correct measurements of the surveyors movement from all the options are; m∠b = 15° and h ≈ 31.28 ft
<h3>What are the correct elevation measurements?</h3>
From the image attached, we see that;
A surveyor found the angle of elevation from the ground to the top from a point = 33°
Now, the surveyor moves 20 ft towards the building and the angle of elevation becomes 48°. This means that ∠A and 48° are supplementary to each other.
Thus;
∠A + 48° = 180°
∠A = 180 - 48
∠A = 132°
From sum of angles in a triangle;
∠B + 33° + 132° = 180°
∠B = 180 - 165°
∠B = 15°
Using sine rule, we know that;
sin 33/C = sin B/20
Thus;
sin 33/C = sin 15/20
Solving for C gives;
C = 42.22
From trigonometric ratios, h/c = sin 48
h = 42.22 sin 48
h = 31.28 ft

Answer:
B) 20
Step-by-step explanation:
Each number in the equation needs to be a whole number, since you can't have 2.5 marbles or something like that.
2/5 of 16 is 6.4
2/5 of 20 is 8
2/5 of 21 is 8.4
2/5 of 26 is 10.4
Even though 20 is the only one that works, if you wanted to be sure it's right, just divide by three after subtracting 8 (the three remaining marbles.)
20-8=12
12÷3=4
The three remaining numbers would be equal and the amount of yellow numbers is a whole number. 20 is correct
