Help me please this is my test

d = 90

e = 39

f = 141

Please don't be mad if i'm wrong

d = 90

e = 39

f = 141

Step-by-step explanation:

D

d is 90 degrees because you see on the other side of d, there is the right angle symbol. This causes d to also equal 90.

E

e is 39 because of vertical angles theorem.

F

e + f = 180 because of supplementary angles theorem.

39 + f = 180

f = 180-39

f = 141

Hope this helped! If not, please let me know! <3

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
