Answer:
d = 102° , e = 56° , f = 22°
Step-by-step explanation:
d and 102° are vertically opposite angles and congruent , so
d = 102°
e and 56° are vertically opposite angles and are congruent , so
e = 56°
f, d and e lie on a straight line and sum to 180° , then
f + d + e = 180° , that is
f + 102° + 56° = 180°
f + 158° = 180° ( subtract 158° from both sides )
f = 22°
Answer:
12
Step-by-step explanation:
2+4=6
8-2=6
6+6=12
You can just set y=0 and solve for x. when you do this you should get 1/2x^2=4
x^2=8
x=2.8 and -2.8 ( you have both a positive number and negative number since (-2.8)^2=(2.8)^2 =8
I hope this helps
