Answer:
10.99 m
Step-by-step explanation:
✍️What we are basically asked to solve here is to find the distance between C and D.
To find CD, find the length of BC, and BD. Their difference will give us CD.
Thus, BC - BD = CD.
✍️Finding BC using trigonometric ratio formula:

Opposite side = BC = ??
Adjacent side = 42 m
Thus:

Plug in the values

Multiply both sides by 42


BC = 35.24 m
✍️Finding BD using trigonometric ratio formula:

Opposite side = BD = ??
Adjacent side = 42 m
Thus:

Plug in the values

Multiply both sides by 42


BD = 24.25 m
✍️How much below the top of the tower is the shorter one attached:
Thus,
BC - BD = CD
35.24 m - 24.25 m = 10.99 m

If those lines are absolute value then the answer is 0 if they are supposed to be parenthesis then the answer is -6
Answer:
Option is right
Step-by-step explanation:
Given that bella want to know what the students at her school think of her show. which is the BEST group to survey to find this information
For getting accurate results she must select a random sample without bias
For this option a will not serve since she selects only students she recognizes.
Option B may not be right, as during show on the face they may not give correct opinion
C is right as a random sample is taken
D is wrong as the first 30 students may not be at random.
So option C is right
Yes. If the segment only has 2 points, it can be named both ways.
