: find za/2 a= 0.07

mA=56 degrees

Step-by-step explanation:

Complementary angles adds up to 90 degrees. This imply that

(7x+28)+(8x+2)=90(7x+28)+(8x+2)=90

From this equation, we can find x:

\begin{gathered}15x+30=90\\15x=90-30\\15x=60\\x=\frac{60}{15}\\x= 4\end{gathered}

15x+30=90

15x=90−30

15x=60

x=

15

60

x=4

Now, we can substitute the value for x into the angle mA:

\begin{gathered}mA=(7*4+28)\\mA=(28+28)\\mA=56\end{gathered}

mA=(7∗4+28)

mA=(28+28)

mA=56

whats the question?

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
