Answer:
x = 80 degrees
Step-by-step explanation:
Let's say the angle ABC = 30 degrees and angle BAC = x degrees
angle ACB = 180 - 110
angle ACB = 70 degrees
angle BAC = 180 - angle ABC - angle ACB
x = 180 - 30 -70
x = 150 - 70
x = 80 degrees
Find the area of 2 sides
find the area of adjacent sides
find the area of the ends
and the 3 areas together to find the surface area <span />
X + (7 - 3i) + (5 + 9i) + 13i = 10 - 5i
Subtract 13i from both sides
x + (7 -3i) + (5 + 9i) = 10 - 18i
Subtract (5 + 9i). MAKE SURE YOU SUBTRACT 9i TOO. In other words, distribute the negative and subtract 5 and 9i at the same time.
x + (7 - 3i) = 5 - 27i
Do the same with (7 - 3i). You'll be adding 3i since -(-3i) = 3i.
x = -2 - 24i
Answer:
The equation is 4x + 5 = 2x + 6
Step-by-step explanation:
The solution is
means x = 
Let us put the coefficient of x in the left hand side = 4 and the coefficient of x in the right hand side = 2
∵ 4x - 2x = 2x
Now we need two numerical terms their difference is 1 like 5 and 6 or 6 and 7 or 7 and 8 or 8 and 9
Let us take 5 and 6
∵ 4x + 5 = 2x + 6
- Subtract 2x from both sides
∴ 2x + 5 = 6
- Subtract 5 from both sides
∴ 2x = 1
- Divide both sides by 2
∴ x = 
∴ The solution is 
The equation is 4x + 5 = 2x + 6
