Answer:

1 = 157°

2 = 23°

Step-by-step explanation:

because the angles are supplementary, their angles will add up to 180°
set up the equation (2x-3)+(-5x+423)=180
combine like terms to get -3x+420=180
subtract 420 from 180 to get -3x=-240
divide by three and get x=80
now plug in 80 for x in both equations

Given<br> BAI BD<br> mZCBD = 40 +52<br> m ABC = 82 - 10°<br> Find mZCBD:<br> B<br> D

sergij07 [2.7K]

Answer:

m∠CBD=68°

Step-by-step explanation:

BA is perpendicular to BD, meaning they form a right angle (90°)

This means m∠CBD + m∠ABC=90, or they are supplementary.

We have expressions given for these angles, so

4x+52+8x-10=90

12x+42=90

12x=48

x=4

Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.

4(4)+52=68

m∠CBD is 68°.

tavon has a $15 gift card that lose $3 for 30- day period It is not used. he has a $40 that loses $1.50 for each day period it i

Anna11 [10]

The number of 30- period until the value if the give card be equal is 20 30- day period

<h3>How to write and solve equation</h3>

let

Number of 30- day period = x

Card 1:

50 - 2x

Card 2:

40 - 1.50x

50 - 2x = 40 - 1.50x

50 - 40 = -1.50x + 2x

10 = 0.50x

divide both sides by 0.50

x = 10/0.50

x = 20

In conclusion, it will take 20 30- day period until the value of the given card can be equal.

Complete question:

Tavon has a $50 gift card that loses $2 for each 30-day period it is not used. He has a $40 card that loses $1.50 for each 30-day period it is not used.
