ANSWER: 119
180 - 71 - 48 = 61
180 - 61 = 119
Answer:
27
Step-by-step explanation:
135 divided by 5 (divide both sides by 5)
2 x 4 = 8
2 x X = 2x
so 8 + 2x
Answer:
irrational
Step-by-step explanation:
You can't multiply it with 2 same digits
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)
