Answer:
110°, 35° and 35°
Step-by-step explanation:
Sum of internal angles of a triangle always is 180°
then,
180° - 110° = 70°
and it's an isosceles triangle, the other two angles are equals to 35° (70° / 2)

Please help with this postulate! :)
Answer:
C. ASA postulateStep-by-step explanation:
We observe two angles and the included side of ABC are congruent to two angles and the included side of DBE:
∠A ≅ ∠D∠C ≅ ∠ EAC ≅ DEThis is called ASA
Answer:
ASA postulate
Answer C is correct
Step-by-step explanation:
<ACB = < BED (Angle)
AC = DE (Side)
<CAB = < BED = 90° (Angle)
Therefore,
ABC triangle is congruent to DBE triangle according to ASA postulate.

Maintaining the chlorine balance in the pool prevents bacteria from growing in the water. The basic
balance of chlorine to water is a concentration of 3 mg/Liter ( 3PPM).
John has a pool 16 meters long, 5 meters wide and 2.4 meters deep. How much chlorine does John
need to pour into the pool?
Answer:
Step-by-step explanation:
The volume of the pool:
16 * 5 * 2.4 = 192
1 liter = 0.001 cubic meters
There are 192 cubic meters in the pool.
Therefore, John needs to pour 0.192 liters of chlorine into the pool.

Evaluate and match each expression on the left to its value on the right, when x = 9 and y = 6.
12 - x
x + 3y
4y - 10
1/3xy
Answer:
12 - x= 3
x + 3y = 27
4y + 10 = 34
1/3xy = 18
Step-by-step explanation:
evaluating where x = 9 and y = 6
12 - x
12 - 9 = 3
x + 3y
9 + 3(6) = 9 + 18 = 27
4y + 10
4(6) + 10 = 24 + 10 = 34
1/3xy
1/3(9* 6 ) = 54 / 3 = 18
The values of the expressions are given below:-
12 - x= 3
x + 3y = 27
4y + 10 = 34
1/3xy = 18
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Evaluating where x = 9 and y = 6
1) 12 - x
12 - 9 = 3
2) x + 3y
9 + 3(6) = 9 + 18 = 27
3) 4y + 10
4(6) + 10 = 24 + 10 = 34
4) 1/3xy
1/3(9* 6 ) = 54 / 3 = 18
Therefore, the values of the different expressions are solved above.

[tex]\\ \sf\longmapsto x=40[/tex]
Angles are
180-80=100°x+5=40+5=45°x-5=40-5=35°No sean was wrong
Answer:
Sean is not correct. The answers are 100°, 35° and 45°.
Step-by-step explanation:
In my working, I labeled the part without a variable as a°.
Step 1: a° + 80° = 180° ( angles on a straight line sum up to 180° )
Step 2: a° = 180° - 80°. This is because 80 moves from the left side of the equation to the right side of the equation which affects it's sign( from + to -)
Step 3: a° = 100° . Subtract 80 from 180.
So we know that 100 is correct. Let's find the remaining angles.
Step 4: a° + ( x - 5 )° + ( x + 5 )° = 180° ( angles in a triangle sum up to 180°)
Step 5: 100° + x - 5° + x + 5° = 180°. Fix in the values of each variable correctly. Here we only know the value of variable a.
Step 6: (100° - 5° + 5°) + (x + x) = 180°. Group like terms to make calculations easier.
Step 7: 100° + 2x = 180°. -5+5 is the same as 5-5 which would give you 0. 0 + 100° is 100°.
Step 8: 2x = 180° - 100°. Move like terms to one side.
Step 9: 2x= 80°. Subtract 100° from 180° to get 80°
Step 10: 2x/2 = 80°/ 2. Divide both sides by 2.
Step 11: x= 40°. But this isn't the final answer. This is just the answer for all the x you see in the diagram. So fix in the values correctly.
Step 12: ( x-5° ). State it for your teacher to know which question you are given an answer to. From our calculations, we know that x = 40°.
Step 13: (40° - 5°)
Step 14: ( 35°). 40 minus 5 is 35.
Step 15: 35°. multiply the figure in the bracket by one. We can't leave our answer in the bracket.
Step 16: (x + 5). Using the same knowledge, fix in the values and do as the operation sign says.
Step 17: ( 40° + 5 °)
Step 18: (45°)
Step 19: 45 °
Step 20: Sean is not right because the angles in the triangle are 100°, 35° and 40°.

London is standing in a stadium and has the option of running up a staircase or down a staircase for exercise. The function f(x)=\frac{1}{25}\big(\left|6x\right|+4x\big)f(x)= 25 1 (∣6x∣+4x) will determine how many calories London will burn if she runs up xx steps. Use a negative value for xx if she runs down the stairs. Find and interpret the given function values and determine an appropriate domain for the function.
The domain of a function is the set of input values, the function can take.
The domain of the function is: [tex]\mathbf{(-\infty,\infty)}[/tex]
The function is given as:
[tex]\mathbf{f(x) = \frac{1}{25}\big(\left|6x\right|+4x\big)}[/tex]
The above function represents the number of steps she runs or up down from her current position.
Because she can move in either directions (i.e. up or down), then it means that, the domain of the function is: [tex]\mathbf{(-\infty,\infty)}[/tex]

Answer:
f(x) = 8x
Step-by-step explanation:
The linear equation given in the form of a table is shown as:
[tex]\left[\begin{array}{ccc}x&f(x)\\3&24\\4&32\\5&40\\6&48\end{array}\right][/tex]
Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):
24 ÷ 3 = 8
32 ÷ 4 = 8
40 ÷ 5 = 8
48 ÷ 6 = 8
Because the quotient for each relation is 8, the linear equation can be written as f(x) = 8x.
