Mathematics
1 answer:
Zielflug [23.3K]3 years ago
5 0

Answer:

Step-by-step explanation:

( x )° + 60° + ( x - 20 )° = 180°

x + 60 + x - 20 = 180

2x + 40 = 180

2x = 140

x = 70

m ( ∠A ) = 70°

m ( ∠B ) = 50°

m ( ∠C ) = 60°

Find the point of intersection:<br> 3x=y-2<br> 6x=4-2y
IgorC [24]
Answer: (0, 2)

3x = y - 2
6x = 4 - 2y

3x = y - 2
- y - y
-y + 3x = - 2
- 3x - 3x
-y = - 3x - 2
/-1 /-1
y = 3x + 2


6x = 4 - 2y
+ 2y + 2y
2y + 6x = 4
- 6x - 6x
2y = - 6x + 4
/2 /2
y = -3x + 2


y = 3x + 2
y = -3x + 2


3x + 2 = -3x + 2
- 2 - 2
3x = -3x
/3 /3
x = 0


y = 3x + 2
y = 3(0) + 2
y = 2

(x, y) --> (0, 2)

Therefore, the two equations intersect at (0, 2)



Hope this helps!

1 divided 5/12=-3/10
emmasim [6.3K]

Answer:

t = - 1/8

Step-by-step explanation:

t ÷ 5/12 = - 3/10

t × 12 ÷ 5 = - 3/10

12t/5 = - 3/10

12t × 10 = -3 × 5

120t = - 15

t = - 15/120

t = - 1/8

Thus, t divided 5/12 = - 3/10 => -1/8
