Answer:
2 : 15 x 2 = 4 : 30
Step-by-step explanation:
You get the ratio 4:30 by multiplying both numbers of the original ratio by 2.
2x2= 4
2x15=30
So in conclusion, the answer to the problem is 4 : 30.
Sum of the interior angles of any triangle equal to 180 degrees thus :
60 + 70 + 8x + 2 = 180
8x + 132 = 180
Subtract both sides 132
8x + 132 - 132 = 180 - 132
8x = 48
Divide both sides by 8
8x ÷ 8 = 48 ÷ 8
<h2>x = 6 </h2>

Answer:
x = 1 and y = -2
Step-by-step explanation:
Given that,
2x-3y = 8 ..(1)
4x+3y = -2 ..(2)
Add equation (1) and (2),
2x-3y+4x+3y = 8+(-2)
6x = 6
x = 1
Put the value of x in equation (1).
2-3y = 8
2-8 = 3y
-6 = 3y
y = -2
Hence, the value of x is 1 and that of y is -2.
