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>
Hope this helps you
All you need to solve these is a knowledge of the 3 main trigonometrical ratios.
I a right angled triangle where A is a non right angle:-
sin A = opposite / hypotenuse (hypotenuse is the sloping side)
cos A = adjacent / hyptenuse ( the adjacent side is the one the angle 'sits' on)
tan A = opposite / adjacent ( the opposite side is the one opposite the angle)
So to find the length of segment x in the first problem use
sin 61 = x / 50
then
x = 50*sin61 = 43.73
and to find the length of y:-
cos 61 = y / 50
y = 60 cos 61 = 24.24
The other questions can be solved in a similar way.
Answer:
f(- 3) = g(- 3)
Step-by-step explanation:
f(x) and g(x) are equal at the point of intersection.
When x = - 3 , f(- 3) = - 4 and g(- 3) = - 4
Thus
f(- 3) = g(- 3)

z =(16-√188)/2=8-√ 47 = 1.144
z =(16+√188)/2=8+√ 47 = 14.856
Answer:
a=75
Step-by-step explanation:
85^2-40^2=5625
then the square root of that is 75
