Question

find M angle 1 if M angle 5 equals 142 + m angle 4 equals 65

Answer 1

Answer:

Here, m∠5 + m∠2 = 180 [ Supplementary Angles ]142 + m∠2 = 180m∠2 = 180 - 142 = 38Now, m∠2 + m∠3 + m∠4 = 180 [ Angles in a Triangle ]38 + m∠3 + 65 = 180m∠3 = 180 - 103m∠3 = 77Again, m∠3 + m∠1 = 180 [ Supplementary Angles ]m∠1 + 77 = 180m∠1 = 180 - 77 = 103

In short,

Your Answer would be 103 Hope this helps!
