Question #e080e

Answer 1

55 degrees

Explanation:

The sum of angles in a triangle is 180 degrees, thus the sum of all the angles is 180 degrees.
Thus by doing simple math calculations:
`angle 1 + angle 2 + angle 3 = 180`
`125 + angle 3 = 180`
therefore,
`angle 3 = 180-125= 55`

Answer 2

`55^@`

Explanation:

`"the sum of the 3 angles in a triangle "=180^@`

`"since 2 of the angles add up to"125^@`

`"then the third angle "=180^@-125^@=55^@`
