Point slope is y-y1=m(x-x1) where m is slope and x1 and y1 are the given x and y values.
y-(-1)=-3(x-7)
y+1=-3(x-7)
Final answer: B
Answer:
-1 / 13
Step-by-step explanation:
(x 1,y1) = (-10,5)
(x2, y2) = (3,4)
y2 - y1 / x2 - x1
<span>sin θ = opposite/hypotenuse
P(18,24) lies in the first quadrant as both are positive.
x=18
y=24
Hypotenuse = sqrt (18^2 + 24^2)
</span><span>Hypotenuse = 30
</span><span>sin θ = 24/30
</span><span>sin θ = 4/5
</span>θ = sin^-1 (4/5)
<span>θ = 53.13 degrees</span>
AB∥CD and m∠4=85°.
so
<1 = 180° - 85°
<1 = 95°
Because AB∥CD so <5 = <1 = 95° (corresponding angles are equal)
Answer
<5 = 95°
