Respuesta :

[tex]\angle 4 = \frac{1}{2} (46 + 42)[/tex]

[tex]\angle 4 = 44[/tex]

[tex]\angle 1 = 180 - 44 = 136 \textdegree[/tex] . [ Adjacent angles on a straight line add up to 180° ]



Answer:

[tex]m\angle 3=136^{\circ}[/tex]

Step-by-step explanation:

We are given that

Measure of intercepted arc are

[tex]46^{\circ},42^{\circ}[/tex]

We have to find the measure of angle 3.

We know that

Internal angle=half the sum of measures of its intercepted arc.

Using this property

Measure of angle 4=[tex]\frac{1}{2}(46+42)=44^{\circ}[/tex]

Measure of angle 4 +measure pf angle 3=180 degrees (linear pair)

Substitute the values then we get

[tex]44^{\circ}+m\angle 3=180^{\circ}[/tex]

[tex]m\angle 3=180-44=136^{\circ}[/tex]

Hence, the [tex]m\angle 3=136^{\circ}[/tex]
