Answer:
n= 24
Step-by-step explanation:
n +7 =31
Both side -7
n+7 -7 =31-7
n= 24
Recall that all three angles in a triangle equals 180.
Knowing this, we just have to add up all the angles and figure out what the value 'x' is.
(x-22 + x-17 + 3x+19) = 180
Simplify:
5x - 20 = 180
Add 20 to both sides:
5x = 200
Divide both sides by 5:
x = 40
Now that we found the value for x, we need to solve for angle A.
Simply input the value of 'x' into angle A's equation:
40 - 22 = 18
Angle A = 18 degrees
Good luck! If you need me to explain anything, just ask :))

Answer:
Its E.(3 × 4) + 1 × (2 × 5) + 3.
Answer:
The correct answer is C. 224
Step-by-step explanation:
Sn = n/2 (2*A1 +d(x-1))
S7=7/2(2*17+5(7-1))
S7=7/2(34+30)
S7=7/2(64)
S7=7*64/2
S7=7*32/1
S7=224

Answer:
(1,3)(1,4)
Step-by-step explanation:
One input cannot have two outputs so one x-value cannot have two y-values.
