Answer:
sin(x) = cos(y)
Step-by-step explanation:
Let's figure out what sin(x) and cos(y) are before we figure out the relationship.
Sine is opposite / hypotenuse. Here, the opposite side to angle x is 12 and the hypotenuse is 13. So, sin(x) = 12/13.
Cosine is adjacent / hypotenuse. Here, the adjacent side of angle y is 12 and the hypotenuse is 13. So, cos(y) = 12/13.
Now we can see the relationship: sin(x) = cos(y)
In fact, for any right triangle with angles 90°, α°, and β°, where α and β can be any angle degree that add up to 90, the following relationships are true:
sin(α) = cos(β)
and
sin(β) = cos(α)
Answer:
1
Step-by-step explanation:
p + 9 - 9 ÷ q - 9
p = 4 q = 3
= 4 + 9 - 9 ÷ 3 - 9
= 4 + 9 - 3 - 9
= 1
Answer:
4u+16
Step-by-step explanation:
first multiply the outside bumber(in this case its 4) by each of the numbers and variables inside. (making u turn into 4u) and ( making 4 turn into 16 bcs 4x4=16
TO figure out, we need to plug in x=0 and then check if y = 7.
And the answer is B, y = x + 7, <span>because at x=0, we have y = 0 + 7 = 7, which matches the given point (0,7)</span>
