Answer:
x = 23°
Step-by-step explanation:
90 = 3x - 9 + x + 7
90 = 4x - 2
92 = 4x
x = 23°

Answer:
A. 
Step-by-step explanation:
We have that, ΔABC is transformed to get ΔA''B''C''.
We see that the following transformations are applied:
1. Reflection across x-axis i.e. flipped across x-axis.
Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.
2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.
So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.
Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.
Answer:
Proving a trigonometric identity refers to showing that the identity is always true, no matter what value of x x x or θ \theta θ is used. Because it has to hold true for all values of x x x, we cannot simply substitute in a few values of x x x to "show" that they are equal.

Math
Answer:
307cm²
Step-by-step explanation:
This is a composite firgue so we need to split the two shapes, then find the area of both.
find the area of the rectangle
A=b*h
A=18*10
A=180
then find the area of the semicircle
A=1/2Pi*r²
A=1/2Pi*81
A=127.75 (We need to find the radius of the semicircle then square it)
then add the two areas 180+127.75=307.75
find the closet unit its
