Y= -6 might be the answer idk
The cosine of an acute angle in a right triangle <span> is the ratio of the length of the adjacent side to the length of the hypotenuse.
</span>If cos(x)=1/2, then:
the adjacent side = 1
the hypotenuse = 2
<span>By the Pythagorean theorem:
</span>the opposite side = √(2² - 1²) = √(4-1) = √3
The sine<span> of an angle is the ratio of the length of the opposite </span>side<span> to the length of the hypotenuse, so:
</span>sin(x) = opposite/hypotenuse = √3/2
The tangent<span> of an angle is the ratio of the length of the opposite side to the length of the adjacent side:
</span>
tan(x) = opposite/adjacent =√3/1 = √3
Y=5. Just substitute 1 in for x because a coordinate in (x,y) and then when you do that you get ...
y=3(1) +2
y=3+2
y=5
(1,5)
Answer:
2/7
Step-by-step explanation:
For the president position, there are 4 females from a total of 7 people.
For the vice president position, there are 3 males from 6 people left over.
So the probability is 4/7 × 3/6 = 2/7.
