Answer:

a) m∠3=113°

b) x=8 (but check below)

Step-by-step explanation:

a) we know m∠1=m∠5

6x-5=5x+7

x=12

we also know m∠1+m∠3=180°

plug x into the formula for m∠1

m∠1=67

m∠1+m∠3=180°

67+m∠3=180°

m∠3=113°

b) Again, we know since those lines are parallel that m∠4=m∠8

x²-4x=32

x²-4x-32=0

(x-8)(x+4)=0

x=8 or x=-4

i think (not 100% sure about this part lol) but x cannot be negative so it's 8

again i'm not sure but it is either 8 or 8,-4.

Write each of the following expressions without using absolute value. |z−6|−|z−5|, if z<5
Andre45 [30]

Answer: 6 - 5

<u>Step-by-step explanation:</u>

|z - 6| - |z - 5|    ; z < 5

Since z < 5, then

|z - 6| will be the absolute value of a negative number. Replace the absolute value with a negative and parentheses:

-(z - 6) =  -z + 6

|z - 5| will be the absolute value of a negative number. Replace the absolute value with a negative and parentheses:  

-(z - 5) = -z + 5

Now subtract them without the absolute value signs:

-z + 6 - (-z + 5)

Distribute the negative sign:

-z + 6 + z - 5

-z + z = 0 which leaves:

6 - 5

Use the diagram to find the measures of each angle. Explain your reasoning.
Likurg_2 [28]

Answer:

angle ABC is 130 degrees

Step-by-step explanation:

This is the quickest and simplest way to gind the answer.

Angle CBD and angle ABC are linear pairs. Linear pairs are supplementary meaning angle CBD and angle ABC equal 180 degrees. Since angle CBD is 50 degrees and you know both angles need to add up to 180 degrees all you need to do is subtract 180 from 50 degrees.
