Answer:
68.0°
Step-by-step explanation:
The tangent function relates the sides of a right triangle to the angle:
Tan = Opposite/Adjacent
The mast is opposite the angle of elevation, and the shadow is adjacent, so you have ...
tan(angle) = (42 ft)/(17 ft)
The inverse tangent function is used to find the angle whose tangent is a particular value.
angle = arctan(42/17) ≈ 67.964°
The angle of elevation is about 68.0°.

Step-by-step explanation:
<u><em>Given:</em></u>
Which of the following options have the same value as 5% 35, percent of 35?
<u><em>Following Options:</em></u>
<u><em>Solve:</em></u>
%
Thus the following options:
[ False x ]
5 does not equal 5%
[True √ ]
%
[ False x ]
[True √ ]
%
[ False x ]
Therefore, the options [B] and [D] is True.

Answer:
55 meters squared
Step-by-step explanation:
SA = sum of all the areas of the sides
The pyramid has four faces, which we have to add together:
SA = 3(long face area) + base area
Area of a triangle = 1/2 base * height
Area of the base = 1/2 * 3.5 * 4 = 7 meters squared
Area of a long face = 1/2 * 8 * 4 = 16 meters squared
Coming back to our surface area formula, we can plug those areas in:
SA = 3(long face area) + base area
= 3(16) + 7 = <u>55 meters squared</u>
B I’m pretty sure sorry if wrong
