Answer:
x = 16 y = 22.627 (or 16
)
Step-by-step explanation:
cos(45) = 16/y
y = 16/cos(45)
y = 22.627
tan(45) = 16/x
x = 16/tan(45)
x = 16
*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)
Answer:
I believe the answer is 1/2
Step-by-step explanation:
4*3=12+2=14,14/3
1*3=3+1=4
14/3+4/3=18/3 divided by 2=6/3 simplified to 1/2
I got the 6/3 by dividing 18 by 2 and 3 by 1
Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x
Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ± 
= ± 2
The number is - 2 or 2
Answer:-21
Step-by-step explanation:
23+22=45
45-24=21
then flip 24 and 45 to get negative
