Solve for y.
a. 10
b.12
c. 15
d. 18

Option A is the correct answer.

The value of y is:

                A.  10

From the figure we could see that:

   3x=90°

so on dividing both side of the equation by 3 we obtain:

  x=30°

and we see that ∠DBC=90°

Hence, we get:

2x+3y=90

on putting the value of x in the expression we get:

2×30+3y=90

i.e.  60°+3y=90°

⇒  3y=90°-60°

⇒  3y=30°

on dividing both side of the equation by 3 we obtain:

y=10°

         Hence, the value of y is:

                        A. 10

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
