Answer:
25. If you look at angle B from the first figure you see a square that indicates a 90 degrees angle, thus the figure shown is a right triangle. You can also see that angle C is said to have 60 degrees. a right triangle has a total angle of 180 degrees. so, 180 - 90 - 60 = 30 degrees. Therefore, angle A is 30 degrees.
27. Now you want the measure of the hypotenuse, and you know this a right triangle. so, simply use the law of sines to find the measure of AC :
4cm/sin(60) = AC/Sin90
AC = 4.62 cm
29. angle z is in the other figure and same stuff, just substract the angles, you have 90 degrees and 30 degrees... 180 - 90 - 30 = 60 degrees
31. Angle Y = 90 degrees
this value is already given, it's the little square that indicates a 90 degrees angle.
26. 5 cm
28. 90 degrees
30. You already found AC, use the pythagorean theorem. sqrt((4.62)^2 - 4^2) = 2.31 cm
32. use pythagoras again, square root(5^2 - 3^2) = 4
So as you can see all the measurements are the same because if you see at the very top of your figures it says ABC = XYZ which means pretty much that they have the same values (notice that there is a little something added to the = sign, watch out for that because that's what indicates that two figures are equal in terms of angles and measures.
Answer:
Hope it will help you a lot.
First find the slope
which is y2-y1/x2-x1
= 3/5
and equation of line in point form is
y-5=3/5(x+3)
intercept from here we get 34/5
so equation in slope intercept form is
y= 3/5x+34/5
Answer:
c. $3866
Step-by-step explanation:
Put 8 where n is and do the arithmetic.
A(8) = $3300(1.02^8) = $3386
Answer:
f(x) is neither odd nor even function
Step-by-step explanation:
we are given
Firstly, we will find f(-x)
we can replace x as -x
we get
now, we can simplify it
we can see that
it is neither equal to f(x) nor -f(x)
we know that
For even:
For odd:
so, f(x) is neither odd nor even function
