Point D is the incenter of triangle BCA If mFDG 136 what is the measure of FHG class=

Respuesta :

Given:

Point D is incenter of ΔBCA.

m∠FDG = 136°

To find:

The measure of ∠FHG

Solution:

Angle subtended by the arc at the center is twice that subtended on the remain part of the circle.

[tex]\Rightarrow m\angle FDG = 2 m\angle FHG[/tex]

Divided by 2 on both sides.

[tex]$\Rightarrow \frac{1}{2} m\angle FDG = \frac{1}{2} \times 2 m\angle FHG[/tex]

[tex]$\Rightarrow \frac{1}{2} m\angle FDG = m\angle FHG[/tex]

Substitute m∠FDG = 136°

[tex]$\Rightarrow \frac{1}{2} (136^\circ)= m\angle FHG[/tex]

[tex]$\Rightarrow 68^\circ= m\angle FHG[/tex]

The measure of ∠FHG is 68°.

Answer:

the correct answer is 68

Step-by-step explanation:

you just have to divide 136 by 2 and you will get 68
