Question

How do i do this correctly? like all steps and answer

Answer 1

• <IGH=<BGD=42°(Opposite)

Let <IHG=x

Now sum of two interior angles =exterior angle

$\\ \sf\longmapsto x+42=99$

$\\ \sf\longmapsto x=99-42$

$\\ \sf\longmapsto x=57°$

Answer 2

Let us keep the value of,

→ IHG = x

Now we have to,

→ find the required value of IHG

The opposite angle of x,

→ 42°

General formula,

→ Sum of two interior angles = exterior angle

Formula we use,

→ IHG + BGD = CIH

→ ( x + 42° = 99° )

The required value will be,

→ x + 42° = 99°

→ x = 99° - 42°

→ [ x = 57° ]

Hence, 57° is the value of IHG.
