Answer:
Step-by-step explanation:
Let
h -----> the height of the building
x -----> the horizontal distance between the building and the tower
we know that
solve for x
-----> equation A
solve for x
------> equation B
equate equation A and equation B and solve for h
![h[tan(80.38\°)+tan(65.05\°)]=(650)tan(65.05\°)](https://tex.z-dn.net/?f=h%5Btan%2880.38%5C%C2%B0%29%2Btan%2865.05%5C%C2%B0%29%5D%3D%28650%29tan%2865.05%5C%C2%B0%29)

Answer: 7^5 or 7 to the fifth power.
Step-by-step explanation: This is an exponent meaning you count the 7’s and in the first picture there’s 5 7’s. This means that the number your putting to a power is the yellow box so that’s 7 and the exponent is 5 not 4 because if you did 7 to the first power it’s still 7 so it would be 7 to the 5th power or 7^5
Answer:
This is important because, the first few numbers might seem to follow a pattern but subsequent numbers might reveal a change in the rule.
Step-by-step explanation:
When studying patterns it is important to evaluate all the figures holistically instead of drawing conclusions based on just the first few numbers because there might be a change in what we felt was obvious on close observance of all the numbers. For example, observe the pattern;
2,4,6, 10, 14, 18, 20, 22, 24
The first two numbers show the addition of two. If a person decides to add 2 to all the figures, he would be wrong because after the first three figures, he would have to add 4 to the numbers.
