Answer:
144
Step-by-step explanation:
20×12=240
add 4 to 20 and 12
makes a new rectangle 24×16
24×16=384
384-240=144
Answer: The answer is 12
Step-by-step explanation: because 5+5+2=12.
Answer:
3 años 4 meses
4 primer año
4 segundo año
4 tercer año pero nos falta 4 meses 4/12 = .33333 esto x 4 los meses = 1.3333
____
13.3333
7200 * .133333= 959.9976 por aproximacion son 960
7200+960 = 8160 Es el monto producido
Opcion C
Answer:
2x+20 + x+40 = 180
Step-by-step explanation:
The angles are supplementary so they add to 180
2x+20 + x+40 = 180
Answer:
The correct answer is m∠2 = 120°
Step-by-step explanation:
There is a triangle rule that states the outer angle of an angle in a triangle is equal to the sum of the remaining two angles in that triangle, which means that m∠2 = 52° + 68° = 120°. This can be proven correct because the sum of two of the angles in the triangle is 120°, which means the final angle is 60°. Since m∠2 is the outer angle of 60°, that means it will be 180° - 60° or 120°.
