Please help if you can thanks ^^

Given:

AD is an angle bisector in triangle ABC. $m\angle CAB=44^\circ, m\angle ACB=72^\circ, m\angle ABC=64^\circ$ .

To find:

The value of $m\angle ADC$ .

Solution:

AD is an angle bisector in triangle ABC.

$m\angle CAD=m\angle BAD=\dfrac{m\angle CAB}{2}$

$m\angle CAD=m\angle BAD=\dfrac{44^\circ}{2}$

$m\angle CAD=m\angle BAD=22^\circ$

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.

Using angle sum property in triangle CAD, we get

$m\angle CAD+m\angle ADC+m\angle ACB=180^\circ$

$22^\circ+m\angle ADC+72^\circ=180^\circ$

$m\angle ADC+94^\circ=180^\circ$

$m\angle ADC=180^\circ-94^\circ$

$m\angle ADC=86^\circ$

Therefore, the angle of angle ADC is $86^\circ$ .

The formula E= mgh, where E = gravitational potential energy, m = mass, g = gravity, and h = height, is used to calculate gravit

Sunny_sXe [5.5K]

Answer:

Option 2. h = E/mg.

Step-by-step explanation:

E= mgh

mgh = E

Divide both sides by mg:

mgh / mg = E / mg

h = E/mg.

Can anyone find the value of b?

Pachacha [2.7K]

Answer:

$b=56$

Step-by-step explanation:

Angles in a straight line add up to 180°.

$180-99$

$=81$

Angles in a triangle add up to 180°.

$180-81-43=b$

$56=b$
