Answer:
s = -3, -7
Step-by-step explanation:
Answer:
2*√2
Step-by-step explanation:
You need to use the trigonometrical function of angle (You should use the side sqrt2 and x to find the x). Take any acute angle (for example, 60 degrees)
The cos of this angle is equal to the ratio of adjoined leg (sqrt2) to the hypotenude (the side opposite to right angle, it is x)
cos60degrees= sqrt2/ x
1/2= sqrt2/x
x= 2*sqrt2= 2*√2
None, maybe you need to look at the question again and re-post
