∠BED and ∠CEA are vertical angles, so that means they are equal to each other.
∠CEA = 88

∠CEB and ∠AED must equal the same since they are also vertical angles, so we will make them both = x in an equation.

All of these angles will add up to 360° because they form a quadrilateral.
88 + 88 + x + x = 360
Combine like terms.

176 + 2x = 360
Subtract 176 from 360.

2x = 184
Divide both sides by 2.

x = 92

Since ∠CEB is larger than 90°, it is an obtuse angle.

<em><u>2</u></em><em><u>)</u></em><em><u>26</u></em><em><u> </u></em><em><u>KIDS</u></em><em><u> </u></em><em><u>CAN</u></em><em><u> </u></em><em><u>GO</u></em><em><u> </u></em><em><u>.</u></em><em><u>.</u></em>

Step-by-step explanation:

1) one batch=2 1/2 cup flour

therefore batch required in 3 1/2 batch= 5/2×7/2=35/4

=8&3/4cup flour

2)No. of kids can go for $60=8

therefore,no. of kids can go in $1=8/60

Therefore,no. of kids can go in $195=8/60×195=26 kids.
