Answer:
Let
- p : this triangle has two 45 degree angles
- q : it is a right triangle
Step-by-step explanation:
Denote
- r : if this triangle has two 45 degree angles then it is a right triangle
Then, r can be written as follows
Since
is a tautology, you get
and given that
it follows that the negation of r is
- " this triangle has two 45 degree angles and it is not a right triangle".
Then, the correct answer is C.
Answer:
75 + 25d > 250
d > 7
Step-by-step explanation:
Number of signatures needed : > 250
Amount of signatures ready = 75
Exoected number of signatures per day = 25
Number of days, d, needed signatures will be collected ;
Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed
Mathematically,
75 + 25d > 250
25d > 250 - 75
25d > 175
d > 175 / 25
d > 7
Answer:
Z is also 116*
Step-by-step explanation:
The reason for them being the same is because of something called alternating angles. This process allows you to find two angle measurements by just finding one.
Answer: no scale
