x-10= -30
move -10 to the other side
sign changes from -10 to +10
x-10+10= -30+10
x= -30+10

Answer:
angle y = 49°
Step-by-step explanation:
If AB = AD and BC = DC, then the two triangles are isosceles triangles. The altitude from the top to the base divides the top angle into two equal angles, with 90° angles at the base. If angle C is divided into two equal angles (41°) and at the base is a 90° angle, that makes angle CBD 49°. On an isosceles triangle, the two angles opposite to the equal sides are identical. So angle y is identical to angle CBD.
The answer is 60. The formula is v=bxhxh/b or in this case 6x4x15/6. After you multiply the numerator you will get 360 and then you divide by 6 to get your answer: 60.
