Question

Theorems include: vertical angles are congruent points on a perpendicular bisector are equidistant from the segment endpoints

find the m<ACS
find the m<SCE
find the m<FCA​

Answer 1

Question 1

Vertical angles are congruent, so
`m\angle ACS=31^(\circ)`.

Question 2

Angles that form a linear pair add to
`180^(\circ)`, so
`m\angle SCE=149^(\circ)`.

Question 3

Angles that form a linear pair add to
`180^(\circ)`, so
`m\angle FCA=149^(\circ)`.
