Complementary and adjacent.
The two angles are complementary because they add up to 90°. It's given that line JL is perpendicular to line MN, and perpendicular means they form a 90° angle where they intersect.
The two angles are adjacent because they are next to each other.
I think the fourth answer is correct because instead of subtracting 0.25 from c, you could do the opposite, wich is 0.75 x c.
The answer to your question is
3x2+(7-5)-1=7
Answer:
7x-2y=30
Find x when y=1
7x-2=30
7x=32
x= 32/7
or decimal form:
4.57 (rounded to the nearest hundredth)
