Answer:
a = 11.71 ; b = 15.56
Step-by-step explanation:
For this problem, we need two things. The law of sines, and the sum of the interior angles of a triangle.
The law of sines is simply:
sin(A)/a = sin(B)/b = sin(C)/c
And the sum of interior angles of a triangle is 180.
45 + 110 + <C = 180
<C = 25
We can find the sides by simply applying the law of sines.
length b
7/sin(25) = b/sin(110)
b = 7sin(110)/sin(25)
b = 15.56
length a
7/sin(25) = a/sin(45)
a = 7sin(45)/sin(25)
a = 11.71
Answer:
9x^4+3x^2 -6
Step-by-step explanation:
(3x^2-2)(3x^2+3)
expand to remove the bracket
9x^4 + 9x^2 -6x^2 - 6
9x^4 + 3x^2- 6
Answer:
When you barter, you must trade it for something else in order to buy something.
Step-by-step explanation:
Answer: -5 degrees Celsius
Step-by-step explanation:
Temp at 2:00am = -2.7
2:00am is two hours after midnight
During that time the temperature has risen by 1.15 degrees every hour so has risen in total by:
1.15x2 = 2.3 degrees
-2.7-2.3=-5
It was -5 degrees at midnight
Answer:
17,28 %
Step-by-step explanation:
81 .............. 100%
14 ....................x%
x = 14×100/81 = 1400/81 ≈ 17,28 %
