Answer:
Step-by-step explanation:
Recall the Exponent Law:
Solution:
Answer:
True
Step-by-step explanation:
A number and its reciprocal have the same sign.
The cosecant is the reciprocal of the sine.
Therefore, the cosecant has the same sign as the sine.
The whale is 24.54 feet away from the shoreline.
Step-by-step explanation:
Step 1:
The man is 200 feet from the ground and the angle at which he sees the whale is 7°.
So a right-angled triangle can be formed using these measurements. The angle of the triangle is 7° while the opposite side of the triangle measures x feet while the adjacent side of the triangle measures 200 feet.
We need to find the opposites side's length of the triangle.
Step 2:
Since we have the length of the adjacent side and need to calculate the length of the opposite side we use the tan of the given angle.
The opposite side of the triangle = x feet.
So the whale is 24.54 feet away from the shoreline.
Answer:
The length of tape that will be required to go round the 4 pennants will be 20 feet.
Step-by-step explanation:
A scout troop is making triangular pennants for their tents. Two sides of each pennant are 2 feet long and the third side is 1 foot long.
Therefore, the perimeter of the triangular base will be = (2 + 2 + 1) = 5 feet.
So, 5 feet of binding tape will be required to go around the pennant.
Hence, the length of tape that will be required to go round the 4 pennants will be = 4 × 5 = 20 feet. (Answer)
