9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
To do this problem, you gotta cross-multiply. SO,
multiplied by
12 times 14 = 168
21 times 3 = 63
Then the final answer is
Answer:
a=-2
Step-by-step explanation:
5 go to another side by negative sign
and the coefficients of a will added
-16=8a
8 go to the other side
a=-2
The smallest of the 3 interior angles of the triangle is 10 degrees. Note that the diagram is not to scale.
Thus, sin 10 degrees = opp / hyp = 200 m / x
0.1736 = (200 m) / x, or x = (200 m) / 0.1736
= 1152 m (rounded up from 1151.75 m).
