For the first one, Rafiki is correct. Multiply each side by 3 to get x by itself and because 3 isn't negative, the sign stays the same.

For the second one, Duey is right because to get rid of a number in a equation subtract or add (depending on whether the number is positive or negative) from both sides.

For the last one I don't think aby of them are right.

Hope this helps!

Jill is standing at the base of her apartment building. She measures the angle of elevation to the top of a nearby tower to be 4
Greeley [361]
Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters

Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters

Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters

In each diagram the line BD bisects angle ABC. Find the measure of angle ABC​
Goshia [24]

Answer:

80°

Step-by-step explanation:

∠ABC= ∠ABD+∠CBD

as BD bisects ∠ABC, we have

  • ∠ABD=∠CBD
  • 2x+20°= 4x
  • 2x=20°
  • x=10°

∠ABC= 2*4x= 8x= 80°
