Answer:
1. m∠1 = 48°
2. m∠1 = 129°
3. m∠1 = 37°
4. m∠1 = 88°
m∠2 = 42°
m∠3 = 113°
5. m∠1 = 72°
m∠2 = 35°
m∠3 = 24°
6. m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 133°
m∠5 = 81°
7. m∠1 = 41°
m∠2 = 85°
m∠3 = 95°
m∠4 = 85°
m∠5 = 36°
m∠6 = 49°
m∠7 = 106°
8. x = 12°
9. x = 9°
10. x = 5°
11. x = 7°
Step-by-step explanation:
1. 76° + 56° + m∠1 = 180°
∴ m∠1 = 180° - (76° + 56°) = 48°
m∠1 = 48°
2. m∠1 = 67° + 62° = 129°
m∠1 = 129°
3. m∠1 = 152° - 115° = 37°
m∠1 = 37°
4. m∠1 = 180° - (52° + 42°) = 88°
m∠1 = 88°
m∠2 = 42°
m∠3 = 180 - (42° + 25°) = 113°
m∠3 = 113°
5. m∠1 = 180° - 118° = 72°
m∠1 = 72°
m∠2 = 180° - 72° - 73° = 35°
m∠2 = 35°
m∠3 = 73° - 49° = 24°
m∠3 = 24°
6. m∠5 = 180° - m∠52° - m∠47° = 81°
m∠5 = 81°
m∠1 = 81° + 47° = 128°
m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 180° - 47° = 133°
m∠4 = 133°
7. m∠3 = 95°
m∠5 = 180° - 144° = 36°
m∠5 = 36°
m∠6 = 180° - 95° - 36° = 49°
m∠6 = 49°
m∠4 = 180° - 95° = 85°
m∠4 = 85°
m∠2 = 85°
m∠7 = 360° - (38° + 85° + (180° - 49°)) = 106°
m∠7 = 106°
m∠1 = 360° - (85° + 90° + 144°) = 41°
m∠1 = 41°
8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 16·x° - 12° = 180°
16·x = 180°+ 12° = 192°
x° = 192°/16 = 12°
x = 12°
9. (3·x - 5)° + (7·x + 5)° + 90 = 180°
10·x + 90° = 180°
10·x = 180°- 90° = 90°
10·x = 90°
x = 90°/10 = 9°
x = 9°
10. 180 - 151 = 29°
(11·x - 1)° + (20·x - 3)° + 29° = 180°
31·x° + 25° = 180°
31·x° = 180° - 25° = 155°
31·x° = 155°
x = 155/31 = 5°
x = 5°
12. (4·x + 13) + (6·x + 2) + 180 - (14·x - 13)
208° - 4·x° = 180°
208° - 180° = 4·x°
28° = 4·x°
4·x° = 28°
x = 28°/4 = 7°
x = 7°.

as -11°C, 5°C, - 8 °C and 15°C. Find the difference between the maximum and the
minimum temperature.
Answer:
26 degrees Celcius
Step-by-step explanation:
The minimum temperature is -11
The maximum temperature is 15
to get from -11 to 0: add 11
to get from 0 to 15: add 15
11+15 = 26

Classify the number 1/2 into as many categories as it belongs: Natural number, whole number, integer, or rational number.
Answer:
1/2 is a rational number.
Step-by-step explanation:
A rational number can be expressed as a ratio of two numbers. 1/2 is a ratio.
It is also a real number, however you do not list that as a category, so from what you listed, it is only a rational number.

What’s the answer to this ???
Answer:
-5, 3
Step-by-step explanation:
3) 10+3n=20+5n Set up the problem
-3n -3n Subtract 3n from both sides to get n on one side of the equation.
10 =20-2n
-20 -20 Subtract 20 from both sides to isolate n
-10 =2n
/2 /2 Divide both sides by 2 to isolate n
-5 = n
4) 18=2(b+6) Write down problem
18=2b+12 Distribute
-12 -12 Subtract 12 from both sides to isolate b
6=2b
/2/2 Divide both sides by 2 to isolate b
3=b
Answer:
3) 3x+10 = 5x+20
=> 3x-5x= 20-10
=> -2x= 10
=> x = 10/-2
=> x= -5
4) 2(b+6) = 18
=> 2b +12 = 18
=> 2b = 18-12
=> b= 6/2
=> b = 3

A triangular pane of glass has a height of 42 inches and an area of 336 square inches. What is the length of
the base of the pane?
PLEASE HELP IM BEGGING
Answer:
its 16
Step-by-step explanation:
area for a triangle is 1/2 the base times the height.
IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base
so
336 *2 = 42x
672= 42x
672/42=x
16 = x

Which statement is true using Cavalieri’s principles ?
Answer:
One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.

Answer:
5) First you have to find x, then use it with supplementary angles theorem.
6) STQ = 150˚
Step-by-step explanation:
To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):
(2x+8) + (71-x) + 90 = 180˚
x + 169 = 180
Then solve for x:
x = 11
You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.
Now, you only need m∠MTS (2x+8) to find m∠STQ...
m∠MTS + m∠STQ = 180˚ because they are supplementary angles.
Input the found x to find m∠MTS:
(2(11)+8) = 30
Subtract 30 from 180 to find m∠STQ:
180 - 30 = 150
m∠STQ = 150˚
