An isosceles triangle have two equal sides and two equal angles.
<em>The measure of angles in </em><em> are: 20, 20 and 140 degrees</em>
Given that:
I've added as an attachment, triangle
From the attached triangle, we have:
--- base angles of isosceles triangle
So, we have:
--- angles in a triangle
This gives:
Collect like terms
Hence, the angles of are:

Answer:
Basically we need to add all of the inches
Step-by-step explanation:
so...
8 inch ( first day ) + 6 inch ( second day) + 9 inch ( third day )
add all those inches together what do you get?
23 inches in total. So altogether 23 inches of snow fell during the 3-day storm
For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:
With the wind against the speed is:
Rewriting both equations, we have the following system of equations:
Then, solving the system of equations (graphically for example), we have the solution is:
Therefore, jet stream's speed:
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
X =25
since the angles are equal to each other, and the same, you can make each angle equal to each other and solve for x:
5x+7=132
5x=125
X=25
Step-by-step explanation:
(1,5) (5,8)
x,y. x,y
Formula: <u>y2-y1</u>
x2-x1
so...
<u>8-5</u><u>=</u> <u>3</u>
5-1 = 4
so... <u>3</u>
