Answer: see below
Step-by-step explanation:
11.3x=15-2x
We move all terms to the left:
11.3x-(15-2x)=0
We add all the numbers together, and all the variables
11.3x-(-2x+15)=0
We get rid of parentheses
11.3x+2x-15=0
We add all the numbers together, and all the variables
13.3x-15=0
We move all terms containing x to the left, all other terms to the right
13.3x=15
x=15/13.3
x=1+1/7.8235294117647
Answer:
Step-by-step explanation:
This is a right angled triangles and the summation of the other two angles must equal 90°
OR you can also say that the summation of all the angles in a ∆ must give us 180°
Therefore (2x+14) + (4x-26) = 90°
Expanding... By collecting all like terms, we have
2x+4x+14-26-90 = 0
6x - 102° = 0
Therefore, 6x = 102
x = 102/6
x = 17°
