Angle 3 and angle 4 form a linear pair. The measure of Angle 3 is four more than three
mel-nik [20]

Answer:

angle 3. ( x ) is 136°

angle 4 ( y ) is 44° !!

Step-by-step explanation:

Let angle 3 be x and angle 4 be y

Given, Angle 3 and angle 4 form a linear pair

x + y = 180 [ sum of linear pair angle is 180 ] ... ( i )

Also, The measure of Angle 3 is four more than three

The measure of Angle 3 is four more than threetimes the measure of angle 4.

x = 4 + 3y .... ( ii )

Putting value of x from ( ii ) in ( i )

4 + 3y + y = 180

4y = 176

y = 44

Also, x + y = 180 => x = 180 - 44 = 136
