Answer:
-1
Step-by-step explanation:
The slope formula is useful:
m = (y2 -y1)/(x2 -x1)
m = (2 -4)/(0 -(-2)) = -2/2 = -1
The slope of this line is -1.
_____
The points on the line drop 1 unit for each 1 unit to the right.
m = rise/run = -1/1 = -1
Answer:
AB = 27.2
BC = 33.5
AC = 50.4
∠A = 38°
∠ABC = 112°
Step-by-step explanation:
<u>Trigonometric ratios</u>
where:
is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
The interior angles of a triangle sum to 180°
⇒ ∠A + 52° + 90° = 180°
⇒ ∠A = 180° - 90° - 52°
⇒ ∠A = 38°
⇒ ∠ABC + 38° + 30° = 180°
⇒ ∠ABC = 180° - 38° - 30°
⇒ ∠ABC = 112°
