Which of the following is the missing justification?

Montano1993 [528]

Answer:

B and C

2. B Multiplication property of equality

3. C Distributive Property

Step-by-step explanation:

1. Given

$\dfrac{1}{5}\cdot x+6=5$

2. Multiply this equation by 5:

$\left(\dfrac{1}{5}\cdot x+6\right)\cdot 5=5\cdot 5$

Multiplication property of equality

3. Use distributive property of equality:

$\dfrac{1}{5}\cdot x\cdot 5+6\cdot 5=25\\ \\x+30=25$

4. Subtract 30:

$x+30-30=25-30\\ \\x=-5$

Subtraction property of equality.

In circle C, what is mFH? 31° 48° 112° 121°

natta225 [31]

we know that

The measurement of the external angle is the semi-difference of the arcs it comprises.

Step $1$

Find the measure of the arc AJ

m∠BDE= $\frac{1}{2} *[measure\ arc\ AJ-measure\ arc\ BE]$

in this problem we have

m∠BDE= $37\°$

$measure\ arc\ BE=38\°$

substitute in the formula

$37\°$ = $\frac{1}{2} *[measure\ arc\ AJ-38\°]$

$74\°$ = $[measure\ arc\ AJ-38\°]$

$measure\ arc\ AJ=74\°+38\°=112\°$

Step $2$

Find the measure of the arc FH

m∠FGH= $\frac{1}{2} *[measure\ arc\ AJ-measure\ arc\ FH]$

in this problem we have

m∠FGH= $32\°$

$measure\ arc\ AJ=112\°$

substitute in the formula

$32\°$ = $\frac{1}{2} *[112\°-measure\ arc\ FH]$

$64\°$ = $[112\°-measure\ arc\ FH]$

$measure\ arc\ FH=112\°-64\°=48\°$

therefore

the answer is

the measure of the arc FH is $48\°$
