Answer:
h = a * sin α
Step-by-step explanation:
The easiest answer is utilizing Law of Sines: a / Sin A = b / Sin B = c /Sin C
a and ∠α : known
∠AEB = 90°
a / Sin 90° = h / Sin α .. Sin 90° = 1
h = a * sin α
Answer:
We'll use this equation:
b = y - mx then we solve for b by inputting the slope (-2) into "m" and use the "x" and "y" values from the given point. (0, 3)
b = 3 --2*0
b = 3
Then we enter "b" into this equation:
y = mx +b
y = -2x + 3

Answer:
Choose a point with a negative x coordinate and a positive y coordinate.
Step-by-step explanation:
The quadrants are labeled counter clockwise 1, 2, 3, and 4.
Quadrant I - has x and y coordinate both positive.
Quadrant 2 - has x coordinate negative and y coordinates positive.
Quadrant 3 - has x and y coordinates both negative.
Quadrant 4 - has x coordinates positive and y coordinates negative.
Since the point is in quadrant 2, choose a point where x is negative but y is positive like (-3, 2).
