In order to find the value for 'a', we can use the law of cosine, which is given by
From the given triangle, we have
On substituting these values in the above mentioned formula, we get
Thus, the length of a is 19.45
Second option is correct.
Answer:
<h3>The answer is 10.42 %</h3>
Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual mass = 240 g
error = 265 - 240 = 25
So we have
We have the final answer as
<h3>10.42 %</h3>

Infinite. They will never touch
The reciprocal of a number is 1/the number.
Assume that the number is y
Now, we will translate the English wordings of the problem into an equation as follows:
y + (1/y) = 4 x (1/y) (multiply both sides by y to eliminate the denominators)
y^2 + 1 = 4
y^2 = 4-1 = 3
y = +/- sqrt(3) = +/- 1.732
Based on this,
either the number is 1.732
or the number is -1.732
Answer:
e
Step-by-step explanation:
As the figure shows, the triangle are right triangle s. So the choice is e
