Find all the missing angles: a, b, c, d.

morpeh [17]

Answer:

a= 180-60-55=65

we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.

b=180-90-65=25

the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.

c=25

c is 25, because two angles on both sides of a X is the same
