87.5
Tall. /. Shadow
3 / 1.74=. X /. 50.75
Cross multiply
152.25= 3x
Divide by 3
X= 87.5
Answer:
y = -
x + 7
Step-by-step explanation:
Ambos puntos (3, 5) y (6, 3) están en esta línea.
B, C, A are collinear because they lie on the same line.
D, C, A are not collinear because they do not lie on the same line
30°
Here's why:
Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is:
c^2=6^2+36*3 -> c=12
Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30°
