3. Given ABCD ≅ FGHJ and mC = 9x - 7, mH = 5x + 13, find the value of x and the measures of angle C and angle H. Show all work
kondor19780726 [428]

Answers:

x = 5

m∠C = m∠H = 38 degrees

 

 

WORKINGS

 

Given that ABCD ≅ FGHJ

We know that corresponding angles of two congruent quadrilaterals are equal

Therefore,

m∠A = m∠F

m∠B = m∠G

m∠C = m∠H

m∠D = m∠I

 

Given,

m∠C = 9x – 7

m∠H = 5x + 13

 

Since m∠C = m∠H

9x – 7 = 5x + 13

 

Add 7 to both sides of the equation

9x – 7 + 7 = 5x + 13 + 7

9x = 5x + 20

 

Subtract 5x from both sides of the equation

9x – 5x = 5x – 5x + 20

4x = 20

 

Divide both sides of the equation by 4

4x/4 = 20/4

x = 5

 

 

To determine the measures of angle C and angle H

m∠C = m∠H

 

We know that m∠C = 9x – 7

Since x = 5

m∠C = 9(5) – 7

m∠C = 45 – 7

m∠C = 38

 

Therefore, m∠C = m∠H = 38 degrees

A container contains water at temperature 80 degree celcius. After every 10 minutes, the change in temperature is - 4 degree cel
lilavasa [31]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of minutes
 y: final temperature
 We write then the equation that models the problem:
 y = (-4/10) x + 80

 For y = 20 we have:
 20 = (-4/10) x + 80

 Clearing x:
 (4/10) x = 80 - 20

x = (10/4) * 60

x = 150
 Answer:
 
The temperature of the water will be 20 degree celcius after 150 minutes

Please help!!! MAX POINTS I CAN DO i put it in math because i trust the math people more
valkas [14]

Answer:

The 1st Blank is: A pure substance, or simply a substance

The 2nd blank on the left is: Elements

The 3rd blank on the right is: Compounds

The 4th blank which is the second middle one is: A mixture

The 5th blank which is the bottom left one is: Heterogeneous mixture

The 6th blank which is the last one on the bottom right is: Homogeneous mixture

Look at the step-by-step explanation if you get confused at the bottom.


Step-by-step explanation:

The 1st Blank: I would just put a pure substance.

The 2nd blank on the left: They are three characteristics of elements but just put elements.

The 3rd blank on the right: They are three characteristics of compounds but just put compounds.

The 4th blank which is the second middle one is: The characteristics of a mixture but just put a mixture.

The 5th blank which is the bottom left one: Are the characteristics of a heterogeneous mixture but just put heterogeneous mixture.

The 6th blank which is the last one on the bottom right: Are the characteristics of a homogeneous mixture but just put homogeneous mixture.
