Answer:
48
Step-by-step explanation:
If the follows triangle congruence, you look at the two triangles given.
Triangle XYZ is equiangular due to it's 3 congruent angles.
Since Triangle XYZ is equiangular, that means it is also equilateral, meaning each side is congruent.
This means that side XY and Side ZY are equal to XZ and therefore
XY = 11 and ZY = 11.
Then we look at Triangle WXZ. Triangle WXZ has two congruent base angles, meaning it's an isosceles triangle.
By the converse of the isosceles triangle theorem, if 2 angles of a triangle are congruent then the sides opposite those angles are congruent.
This means XZ and WZ are congruent to each other, meaning XZ = WZ.
Since XZ= 11, that means WZ = 11.
Now we have all outside side lengths and we can find the perimeter.
Perimeter = WX + WZ + ZY + XY.
(substitute known values of sides)
11+11+11+15= Perimeter
33+15 = Perimeter
48 = Perimeter
Answer --> 40 : 320
1/9 x 360 = 40
8/9 x 360 = 320
One major problem is that you're not keeping the units like I showed you.
I think you have everything there, except that I have no idea what that '168'
is all about.
Here it is with the units:
(1million seconds / 1)x(1min/60sec)x(1hr/60min)x(1 day/24hr)x(1 yr/365da)
= (1,000,000 x year) / (60 x 60 x 24 x 365) = <em>0.03171 year</em>
Except for that screwy mysterious '168', you have everything there,
and in the right place. Again, I'm going to say that you didn't realize
it, because you dropped all the units and suddenly all you saw was a
bunch of numbers in front of you.
Answer:
right and scalene
Step-by-step explanation:
all the sides are different in length, so it's a scalene triangle, plus, it has a right angle, which makes it a right angled triangle.
