Answer:
a(
+
) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a(+)
Just substitute the values given for each variable
a(+) = (-1)(
+
) ; do the exponents first
a(+) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a(+) = -13 ; and multiply by -1

Answer:
C. 57°
Step-by-step explanation:
All triangles have a sum of 180°.
m∠D + m∠E + m∠F = 180°
35° + m∠E + 88° = 180°
123° + m∠E = 180°
m∠E = 57°
