The angle of measure 1 is equivocal to its adjacent angle, so M<1 = 39 degrees
Because the summation of all angles of a triangle need to be 180 degrees, we can find M<3. We have an angle of 39 degrees and a right angle which is 90 degrees.Therefore M<3 is equal to 51 degrees
Sinx =8/40
in order to solve this you would have to use the inverse which would be Sin^-1(8/40) giving you 11.5
Isosceles triangle, angle P = angle Q.
3x + 10 = x + 52
2x = 42
x = 21
Congruent angles are both x+52=73 degrees. Triangle angles add to 180 so
y = 180 - 73 - 73 = 34 degrees
Answer: 34
