Can’t work out angle 2x-30 i don’t know what this means and is the angle next to 68 a right angle or straight line : would i subtract 180 - 68

x = 63

Step-by-step explanation:

Since AB and CD are parallel lines, then

2y - 30 = 68 ( corresponding angles )

Add 30 to both sides

2y = 98 ( divide both sides by 2 )

y = 49

The third angle in the triangle = 68 ( alternate angles )

The sum of the 3 angles in the triangle = 180°, that is

x + y + 68 = 180 ← substitute value of y

x + 49 + 68 = 180

x + 117 = 180 ( subtract 117 from both sides )

x = 63

i really do not know lamo this is great

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
