Answer: 9.70%
Step-by-step explanation:
The formula to find the percentage error is given by :-
Given : Actual mass of zinc oxide used by pharmacist = 28.35 g
Estimated mass of zinc oxide used by pharmacist =31.1 g
Now,
i.e.
i.e.
Hence, the percentage of error on the basis of the desired quantity.= 9.70%
Question:
What is the value of x? Enter your answer in the box. 68mm 57mm 129.2mm
The image of the triangle is attached below:
Answer:
The value of x is 98mm
Explanation:
It is given that VT = 57, TK = 129.2, YK = 68 and VK = x
Now, we need to find the value of x.
We shall determine the value of x, using angle bisector theorem,
Let us substitute the values, we get,
Switch sides, we have,
Multiply both sides by 57,
Simplifying, we get,
Adding both sides by 68, we have,
Thus, the value of x is 98mm
