your image doesnt enlarge. i zoomed in and i think i see

80 4 x 7 35 5 7 y w z 5 v o 4

is this correct?

if it is then we begin with triangle 80 4 x 7

a straight line is 180* with itself so the angle next to 80 is 180-80=100

angles in a triangle add up to 180 so

x+100+35=180.

x+135=180

x=180-135=45

now the other triangle.

the other triangle has 3 sides the same as this triangle so its the same triangle.

o=x=45

v=100

w=35

because of the two parallel lines

o=y=45

again straight lines give 180* so

you can finish up
