Answer:
∠ 2 = 86°
Step-by-step explanation:
Vertical angles are congruent, thus equating gives
20x - 14 = 17x + 1 ( subtract 17x from both sides )
3x - 14 = 1 ( add 14 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Thus
∠ 2 = 20x - 14 = 20(5) - 14 = 100 - 14 = 86°
Answer:
804.4
Step-by-step explanation:
the formula for the volume of a cube is the side length cubed,
so:
(9.3)(9.3)(9.3) = 804.357
then round it to 804.4
hope this helped!

c
Step-by-step explanation:
Hello :
<span>the numbers are : x , y
x - y = 4...1)
xy = 96...(2)
by (1) : x = y +4...(*)
subsct in (2) : (y+4) y = 96
y² +4y -96 = 0
(y² +2(2y) +2²) -2² -96 = 0
(y+2)² -100 =0
</span>(y+2)² <span>= 10²
y +2 = 10 or y+2 = -10
y = 8 or y = -12 ( refused : x is positif)
y = 8
</span>subsct in (*) : x = 8+4 = 12
<span> the numbers are : 12 and 8
12-8 = 4 and 12×8 = 96</span>
