Okay, so supplementary angles = 180 degrees.
Starting equation : 4y + 7 + 9y + 4 = 180
Combine like terms : 13y + 11 = 180
Subtract 11 from both sides : 13y = 169
Divide 13 from both sides : y = 13
Insert y value into original m<2 equation : 9(13) + 4
Solve : 121 degrees
If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.
4(13) + 7 = 59
59 + 121 = 180
Given:
A figure of a right triangle with perpendicular 500 m and hypotenuse x.
To find:
The value of x.
Solution:
If a transversal line intersect two parallel lines, then alternate interior angles are congruent.
Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.
In a right angle triangle,

In the given triangle,




Round the value to the nearest tenth.

Therefore, the value of x is 777.9 m.
Ok so draw the outline of the figure than count the squares and the ones that look like triangles are only half of one
