Solution

Step 1

For a given angle A

Opposite = 12

Hypotenuse = 15

Step 2

$\begin{gathered} sinA\text{ = }\frac{Opposite}{Hypotenuse} \\ sinA\text{ = }\frac{12}{15} \\ A\text{ = sin}^{-1}(\frac{12}{15}) \\ A\text{ = 53} \end{gathered}$

Final answer

A = 53

X over 45 - 7 over 9. X = ?

Degger [83]

Answer:

X=35

Step-by-step explanation:

simplify 7/9

x/45-7/9=0

simplify x/45

x - (7 • 5)/45= x - 35/45

x-35/45=0

add 35 to both sides

x=35

Tell whether the statement is true or false. If w is 25% of Z, then Z:W is 75:25

melamori03 [73]

False.
If w is 25% of z, then w:z would be 25:100, because 25 is 25% of 100.
If Z:W was 75:25, it would be wrong because 25 is 33% of 75, not 25%.
