Answer:
154 sweets
Step-by-step explanation:
Adrian, Ben and Charlie share some sweets in the ratio 5:2:7 and Charlie got 22 more sweets than Adrian.
Let the total number of sweets be x.
Then Adrian gets:
And Charlie gets:
It was given that Charlie got 22 more sweets than Adrian.
This implies that:
Multiply through by 14:

I just did this test the answer is B :-)
You can understand this by two ways
1) through congruency rules
It says that triangle ABE is congruent to DCE
So the corresponding angles are equal
Eg
Angle A to Angle D
Angle B to angle C
Angle E to angle E
So they’re asking the angles AEB and DEC (which are equal as per congruency)
Thus you can equate them
4y-15=69
y=21
2) through vertically opposite angles
Since the triangles’ angles are vertically opposite one another, they are equal.
Then you can equate them the same way
Hope this helped!!
