Answer:
sin is only positive in 1st and 2nd quadrants
Step-by-step explanation:
As you may know, sine is defined as y-term or value in (x, y). You can go see a unit circle.
Remember that sine is y while cosine is x.
Since sine is y, It'd be a horizontal line. And since it's a horizontal line, it intersects two points in a unit circle.
Q1 and Q2 both are positive while Q3 and Q4 are negative.
m∠5 = 142°
Solution:
Line l and m are parallel.
<em>Sum of the adjacent angles in a straight line is 180°.</em>
⇒ 38° + m∠7 = 180°
⇒ m∠7 = 180° – 38°
⇒ m∠7 = 142°
∠5 and ∠7 are corresponding angles.
<em>If two parallel lines are cut by a transversal, then the corresponding angles on the same side are congruent.</em>
⇒ ∠5 ≅ ∠7
⇒ m∠5 = m∠7
⇒ m∠5 = 142°
Therefore m∠5 = 142°.

Answer:
Area and side length of rhombus.
Step-by-step explanation:
Directly proportional: If the first variable is multiplied by a constant, the other will also be multiplied by a constant.
Rhombus is a quadrilateral with equal side lengths.
Area increases with a quadratic relationship as a corresponding length increases if the angles do not change. If side length is multiplied by A, the area will be multiplied by A^2. If side length is doubled, the area will be 4 times greater.
Total cost is usually directly proportional to ticket price.
If number of tickets are doubled, the total cost will double.
Hours worked is usually proportional to money earned.
If one works twice as long, money earned will be twice as much.
Distance is proportional to time spent when speed is constant if travelling in a straight line. If time is twice as long, the distance traveled will double.
