Answer:
m ∠ W is 58.2°
Step-by-step explanation:
Given:
XY = 15
WZ = 22
∠ XZY =25°
To Find:
m ∠ W = ?
Solution:
In right angle triangle Δ XZY, by Sine identity we have
∴ XZ = 35.49
Now in right angle triangle Δ WZX, by tangent identity we have
∴m ∠W =58.2°
Answer:
SAS
Step-by-step explanation:
ΔABD ~ ΔECD is similar through:
S - because ED = CD (Given)
A - same angle ∠D (Statement 2)
S - because AD = BD (Given)

Sorry this just got deleted :( ill post it again

I'm sorry I'm bad at explaining how i solved it
The domain of a function is the set of values for which the function is defined; i.e. the function outputs a value for an input from the domain. That means that we must be able to plug in numbers for x and get numbers from y.
We can't take the square root of negative numbers (ignoring imaginary numbers), so that means we can take the square root of any non-negative number; i.e. we can take the square root of zero, and any positive number.
Therefore, any function that can take in values of x that are zero or more than zero has the same domain as the given function. So
is a function that has the same domain as
.
Answer:
-24
Step-by-step explanation:
g(-2) = 2(-2)
g(-2) = -4
h(4) = 4² + 4
h(4) = 16 + 4
h(4) = 20
g(-2) - h(4)
-4 - 20
= -24
