Step-by-step explanation:
Calculate the hypotenuse( h ) using Pythagoras' identity
h =√(4² + 7²) = √(16 + 49) = √65
sinΘ = 4 / √65 ⇒ cscθ = √65 / 4
cosθ = 7/ √65 ⇒ secθ = √65 / 7
tanθ = 
⇒ cotθ = 
Answer:
8
Step-by-step explanation:
*whispers* (there is a calculator online for that.)
Also the formula is a² + b² = c².
Answer:
3/16 of an onion
Step-by-step explanation:
3/4 onion divided by 4
3/4÷4
Copy dot lip
3/4 * 1/4
3 /16 of an onion
To solve for the variables y and x we substitute the second equation into the first meaning that y = -x +2 you substitute y for (-x+2)
so
(-x +2) = x +4
add x to both sides
2 = 2x + 4
subtract 4 from both sides
-2 = 2x
divide by 2
-1 = x
now plug x back into the original equation
y = (-1) + 4
y = 3
and
y = -(-1) + 2
y = 1 +2
y = 3
there you have it x = -1 and y = 3
Hope this helps ;)
