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° .

You have to separate 3 five times so like 3+3+3+3+3=15
Answer:
.
Step-by-step explanation:
1/4 of $160 is $40. 3/10 of $120 is $36.
5/21 of 84 is $20.16. This leaves him with $63.84.
