Step-by-step explanation:
first you need to know that angle 4 and angle d are the same measurement. so then you have to notice that a straight line is equal to 180 degrees. by knowing this you can make this equation
x+30+ 2x +15= 180
next combine like terms:
3x+ 45=180
next subtract 45 from both sides
3x=135
next divide by 3 on both sides to get x alone. this will give you your answer.
x=45
once you know this plug 45 into you equation to do d the value of the angle 4

It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or 
. Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:
Where x is the amount of water to be added, in ml (milliliters).
Cross multiplication of the above equation will give us:
Dividing both sides by 2 we will get:
Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.
If this is math where is the number or is it just word problem
