Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ = 
Cosθ = 
tanθ = 
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ = 
θ = 
Option (A) will be the answer.
Answer:
40 degrees
Step-by-step explanation:
Because Angle RST is bisected by ray SU it is then split into two even angles and the resulting two angles will be 40 degrees apiece.
Answer:
≈ 16.65 un²
Step-by-step explanation:
The image shows the formula
With the given info you would get ≈ 16.65 un²
Answer:
67 feet^2
Step-by-step explanation:
Surface Area = 2×(4×2.6 + 4×3.5 + 2.6×3.5) = 67 feet^2
So if they are similar then just try to figure out which two sides correspond to each other from the first and then the second triangle.
See how in the above example I did 20 and 5 not 20 and 14 or 20 and 3.5 because they do not correspond with one another.
Then figure out, is x on the mama or baby shape and either multiply the number received from all proportions or divide.
Multiply : small to big ( # missing on the bigger one )
Divide : big to small ( # missing on the smaller one)
