The sum of all the angles of any quadrilateral is 360 degrees
115 + 97 + 58 + missing angle = 360
missing angle = 90 degrees
Hope that helps!
The first option is correct
Standard form starts with the term that has the highest x degree then decreases.
:)))
3x + 7y = 14
Subtract 3x from both sides
7y = -3x + 14
Slope is equal to -3.
Answer:
10x + 12y = 15
12y = 15 - 10x
y = 15 - 10x / 12 (15 minus 10x all divided by 12) [Answer]
