Answer:
114
Step-by-step explanation:
Since DE and EF are equal, DEF is an isosceles triangles.
In isosceles triangle, two angles are equal.
So,
∠F = ∠D = 33
Sum of interior angles in a triangles is 180,
∠D + ∠F + ∠E = 180
33 + 33 + ∠E = 180
∠E = 180 - 33 - 33
∠E = 114
Assuming that the fee is purely based on duration, the equation would look like this:
c= a*p
where c= cost, a= rates per hour, p= hours of parking
Alexandra pays 7$ for 3 hours parking. So, a would be:
c= a*p
7$= a * 3 hr
a= 7$/3hr
Then the final equation would be:
c= (7/3) *p
Answer:
-11
Step-by-step explanation:
Convert -3 2/3 to -11/3
-11/3÷1/3
Dividing by 1/3 is the same as multipling by 3
so the equation becomes
(-11/3)(3)
=-11
well, a and d are true, and b is somewhat false...
angles that are both less than 90 degrees and higher than 0 have to add up to equal 90, not just be less than 90
c, is the same thing. Straight angles are 180 degrees, but supplementary means two angles add up to equal 180 degrees, not just one
so b and c may be true, im not sure
i know that a and d are true, therefore they are not the right answer
