Sin a = 14/50 and cos a = 48/50
Answer:
Parallel sides
Step-by-step explanation:
A rectangle has all of its interior angles equal to each other and inclined at a degree of 90.
The two opposite sides of a rectangle are parallel to each other.
Parallel lines are lines that will never meet, no matter how long that they are extended.
If we can extend the two sides of the rectangle facing each other, we will be able to see that they will never meet no matter how far they are extended.
Thus, the rectangle has 2 pairs of parallel lines
Answer: 446
Step-by-step explanation:
18(2)+410
36+410
446
Let's solve for c.
x2+18x+c=25+c
Step 1: Add -c to both sides.
x2+c+18x+−c=c+25+−c
x2+18x=25
Step 2: Add -x^2 to both sides.
x2+18x+−x2=25+−x2
18x=−x2+25
Step 3: Add -18x to both sides.
18x+−18x=−x2+25+−18x
0=−x2−18x+25
Step 4: Divide both sides by 0.
00=−x2−18x+250
c=−x2−18x+250
Answer:
c=−x2−18x+250
