Explanation:
_____________________________________________________
180 - (39 + 30) = 180 - 69 = 111. This is the measurement of the third angle in the triangle. Note that all angles in a triangle add up to 180° . All triangles have 3 (three) sides and 3 (three) angles.
To find m∠1 :
_____________________________________________________
The only single angle that exists that is supplementary to ∠1 is 69.
So: m∠1 = 180 - 111 = 69 . (Note: since all angles on a straight line are supplementary angles; and supplementary angles add up to 180° .
_______________________________________________________
The answer is: 69° .
m∠1 = 69° .

-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
764 divided by 7 is 109.
1348 divided by 14 is 96.

It’s just asking, what is the high yes leek is f the functions and what’s the lowest peek.
Since the first angle should be 40 degrees more...

We Have in make 90 degrees with the rules, the complement angle must be 25
