Answer:
It should be reported as 20.648%
Step-by-step explanation:
Since we have 2 different observed values hence we shall use an average of the 2 values to report the result
Thus value is 
As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.
Thus the result shall be 20.648%
Abcissa is x, and ordinate is y.
In this case the x is positive, and the y is negative.
Therefore, the answer is "positive, negative"
Answer:
<u>TO FIND :-</u>
- Length of all missing sides.
<u>FORMULAES TO KNOW BEFORE SOLVING :-</u>
<u>SOLUTION :-</u>
1) θ = 16°
Length of side opposite to θ = 7
Hypotenuse = x
≈ 25.3
2) θ = 29°
Length of side opposite to θ = 6
Hypotenuse = x
≈ 12.3
3) θ = 30°
Length of side opposite to θ = x
Hypotenuse = 11
4) θ = 43°
Length of side adjacent to θ = x
Hypotenuse = 12
≈ 8.8
5) θ = 55°
Length of side adjacent to θ = x
Hypotenuse = 6
≈ 3.4
6) θ = 73°
Length of side adjacent to θ = 8
Hypotenuse = x
≈ 27.3
7) θ = 69°
Length of side opposite to θ = 12
Length of side adjacent to θ = x
≈ 4.6
8) θ = 20°
Length of side opposite to θ = 11
Length of side adjacent to θ = x
≈ 30.2
Answer:
(7, - 7 )
Step-by-step explanation:
- 4x + y = - 35 → (1)
- 2x - y = - 7 → (2)
adding the 2 equations term by term will eliminate the y- term
(- 4x - 2x) + (y - y) = - 35 - 7
- 6x + 0 = - 42
- 6x = - 42 ( divide both sides by - 6 )
x = 7
substitute x = 7 into either of the 2 equations and solve for y
substituting into (1)
- 4(7) + y = - 35
- 28 + y = - 35 ( add 28 to both sides )
y = - 7
solution is (7, - 7 )
