Answer:
290,000 is rounded to the nearest ten thousand
This is simple pythagoras, its just a²+b²=c². First you find the hypotenuse, which is 97; now you have the equation: x²+72²=97²
x²=9409-5184
x= √4225
x=65
the answer is 65m

Answer:
(b) tan B = 8/6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Then angle B is involved in tangent and cosine relationships this way:
tan B = 8/6 . . . . . . matches 2nd choice
cos B = 6/10 . . . . . matches no choices
_____
<em>Additional comment</em>
Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.
Answer:
83.15
Step-by-step explanation:
Joey's current grade can be determined by weighting his scores with the weights given and adding the results
Tests = 0.6 x 82 = 49.2
Quizzes = 0.25 x 77 = 19.25
homework = 0.15 x 98 = 14.7
49.2 + 19.25 + 14.7 = 83.15
