X= -3
Solution:
takeaway 4 from each side
x+3=0
subtract 3 from each side
x=-3
Answer:
w=40
Step-by-step explanation:
120*1/3=40
Therefore, w=40
Answer:
y=(0,-45)
x=(-10,0)
Step-by-step explanation:
10 feet and 11 inches is the answer.
Hope this helps! :)
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.
