Answer:

x=5

Step-by-step explanation:

Put everything on one side of the equation and have it equal to 180 degrees.

13x+3+72+8x= 180

Combine like terms

21x+75= 180

Subtract 75 on both sides

21x = 105

Divide by 21 on both sides

x= 5

hope this helped!

Rewrite the expression in the form 6^n 6^-6/6^-5

oee [108]

Answer:

6^-1

Step-by-step explanation:

6^-6 - (-5) = 6^(-6 + 5) = 6^(-1)

A lot of things are going on in this question. Notice how the 5 is handled. It starts off in the denominator as - 5 and when brought to the numerator it becomes -(-5) which makes it + 5.

The answer is then easy. It is 6^(-6 + 5) = 6^-1

You could give the answer as 1/6 but that is not what the question says.

Find the length of BC. Explain how you got it, please! Thanks!

Vinvika [58]

Answer:

BC = 30.73

Here,

$\sf \frac{AB}{BQ} = \frac{CD}{DQ}$

so first solve for QD

$\sf \hookrightarrow \frac{32}{15} = \frac{19.2}{DQ}$

$\sf \hookrightarrow 32(DQ)} =19.2(15)$

$\sf \hookrightarrow 32(DQ)} =288$

$\sf \hookrightarrow DQ =9$

Hence, QD = 9

Now! using Pythagoras theorem,

CD² + BD² = BC²

19.2² + (9+15)² = BC²

BC = √368.64+576

BC = 30.73499634

BC = 30.73 ( rounded to nearest hundredth )
