Question

How do I write down the size of Angles and marked by letters?

Answer 1

we can assume the lines are parallels so both triangles will have equal angles, so:

s=55° and p=x

now if we add 110 and x, we have a line this means

110+x=180

x=180-100

x=80

so p=x=80

and finally, the angles inside a triangle must add 180° so

55+p+t=180

55+80+t=180

135+t=180

t=180-135=45

So the answer is:

p=80°

s=55°

t=45°
