Question

find the unknown marked angles​

Answer 1

Answer:

the other side of 105 angle is 75 degree angle. 75+x=2x. so x=75. 2x=150

Step-by-step explanation:

Answer 2

Answer:

Sum of x and 2x will be 105 degrees (exterior angle).

So,

    x + 2x = 105 degrees

     3x = 105

     x = 105/3

     x = 35 degrees

So, angle x will be 35 degrees and angle 2x will be 70 degrees...
