Mathematics
1 answer:
Iteru [2.4K]3 years ago
5 0

Step-by-step explanation:

Given : m∥n , ∠1= 50° , ∠2= 48° , and line s bisects ∠ABC

To prove = ∠3= 49°

Solution:

In figure, m∥n cut by traversal t.

So,  ∠DEF = ∠ABC(alternative exterior angles)

∠1 + ∠2 = ∠4 + ∠5

∠ABC = ∠1 + ∠2 = 50° + 48° = 98°

Also given that s bisect angles ∠ABC.

∠4 = ∠5

∠ABC = ∠4 + ∠5 = 98°

∠4 + ∠4 = 98°

2∠4 = 98°

∠4 = 49°

∠4= ∠3 = 49° (vertically opposite angles)

∠3 = 49° ,hence proved

Geometry: Write a formal proof, ASAP!!!
yulyashka [42]

{\qquad\qquad\huge\underline{{\sf Answer}}}

Here we go ~

As we can see in the figure, lines m and n are parallel to each other. so we can apply Angle pair properties ~

So,

\qquad \sf  \dashrightarrow \:  \angle1  \cong \angle2

[ they form corresponding angle pair ]

and it's given that :

\qquad \sf  \dashrightarrow \:  \angle2 \cong\angle 3

therefore, by using above information. we can conclude that :

\qquad \sf  \dashrightarrow \:  \angle1 \cong \angle3
