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!!
Answer:
Step-by-step explanation:
Using soh cah toa
Sin=opp/hot
Sin 52°=h/121
h=sin52°×121
h=0.7880×121feet
h=95.348feet
To find the number of perfume bottles that are made of crystal, multiply 99 by 2/3.
An easy way to do this in your head is to divide 99 by 3, and then multiply it by 2.
99/3=33
33*2=66
66 bottles in Tiffany's collection are made of crystal.
