Answer:

x=18

Step-by-step explanation:

Hey There!

So if you did not know all of the angles in a triangle will add up to equal 180

So we use the equation

180=2x+3x+5x

and solve for x

step 1 combine like terms

2x+3x=5x

5x+5x=10x

so now we have

180=10x

step 2 divide each side by 10

180/10=18

therefore x = 18

hope this helps and if you have any more questions feel free to ask :)

We know that all angles in a triangle add up to 180.

5x+3x+2x=180
10x=180
x=18

leave it change it turn it over

$\frac{2}{3}$ × $\frac{5}{4}$

now solve it

$\frac{2}{3}$ × $\frac{5}{4}$ = $\frac{10}{12}$

Find The Value Of x ?

slega [8]

Answer:

1) $x = -1$ || 2) $x = 10$

Explanation:

→ $\log _3\left(\frac{1}{3}\right)=x$

→ $\frac{1}{3} = 3^x$

→ $3^{-1} = 3^x$

→ $x = -1$

→ $\log _3\left(x-1\right)=2$

→ $x - 1 = 3^2$

→ $x -1 = 9$

→ $x = 9 +1$

→ $x = 10$
