Answer:

30°

Step-by-step explanation:

Use that

-the sum of angles in a triangle is 180° and that

-vertical angles are congruent ( angle x and the missing angle in the bottom triangle are vertical)

x= 180-75 -75 = 30°

Y= 10x - 32 what is the x and y value of this equation

Marrrta [24]

Answer:

$y=10x-32 \\ \\ x=\frac{y}{10}+3.2$

Step-by-step explanation:

$y=10x-32$

Because that's the equation given.

To solve for x, isolate the variable and then divide by the coefficient.

$y=10x-32 \\ \\ 10x=y+32 \\ \\ x=\frac{y}{10}+\frac{32}{10} \\ \\ x=\frac{y}{10}+3.2$

If 3 to the power y = x then y = ?

Oksanka [162]

Answer:

$y=\log_3(x)$

Step-by-step explanation:

$3^y=x$

$\ln(3^y)=\ln(x)$

$y\ln(3)=\ln(x)$

$y=\frac{\displaystyle\ln(x)}{\displaystyle\ln(3)}$

but if

$f(x)=\frac{\displaystyle\ln(x)}{\displaystyle\ln(3)}$

then since

$f(3)=\frac{\displaystyle\ln(3)}{\displaystyle\ln(3)}=1$

$f(x)=\log_3(x)$

$y=\log_3(x)$

$3^y=x$

$\log_3(3^y)=\log_3(x)$

$y\log_3(3)=\log_3(x)$

$\text{but }\,\log_3(3)=1, \text{so,}$

$y=\log_3(x)$
