Answer:
4:
a.) 49x^2-36y^2
b.) 9a^2-25b^2
c.) 1/25x^2-49
5: b.) -5x^2-4xy+4y^2
Step-by-step explanation:
Okay seems like you need to find the numbers that are greater than 51
so it says solution set
x + 16 > 51
plug some numbers
so
45 + 16 > 51
61 > 51
so keep adding numbers to find a solution that is bigger than 51
Answer: 21.3m
Step-by-step explanation:
The height of the kite of the ground would be calculated as:
We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.
Therefore, the height of the kite would be:
= 30 sin 40 + 2
= 30 (0.6428 ) + 2
= 19.284 + 2
= 21.284 m
= 21.3 m
Answer:
No
Step-by-step explanation:
No, because supplementary angles add up to 180 degrees, and these two do not.
I believe it is 6 hopefully
