Answer:
Step-by-step explanation:
To find measures of angles m and n
The triangle to the left has three sides of equal length.
This means that it will also have three angles of equal measure.
The internal angles of a triangle sum to 180°
So the internal angles of the left triangle are 180/3 = 60°
The top right angle is made up of one of the 60° angles and angle n
60 + n = 90
n = 30°
Again the internal angles of a triangle sum to 180°, so the right triangle
m + n + 90 = 180
m = 180 - 90 - 30
m = 60°
or we could realize that the top and bottom horizontal lines are parallel because the vertical line on the right makes right angles to both of them.
Knowing that they are parallel, we also know that angle m and the top right 60° angle of the left triangle are opposite internal angles of a line intersecting parallel lines and must be identical angles, therefore
m = 60°
It should be 14/12 or 1 and 1/6
Answer:
6x2 + 9x - 15
Step-by-step explanation:
All you have to do is multiply 3(2x2 + 3x - 5)
When you distribute, you will multiply 3 by 2x2, which is 6x2. 3 by 3x, which is 9x. And 3 by -5, which is -15. Then you can just write them all in order because none of them are like terms that you can combine.
6 goes into 420 70 times.
There were 7 cows before. All you have to do is subtract 13 from 6, which gives you 7. Do you need anymore help??
