If a line is drawn across the shape connecting two of the angles it makes two triangles. The sum of the angles in a triangle is 180 degrees.
Since this shape makes two triangles the sum of the inside angles is 2 * 180 = 360 degrees

(2x - 17) + 90 + x + 59 = 360
combine like terms
3x + 132 = 360
3x = 360 - 132
3x = 228
x = 76

Joelle ordered 12 dozen doughnuts for the honor roll
Serjik [45]

Answer:

The answer is there are 30 glazed donuts

Step-by-step explanation:

there are 12 donuts to a dozen therefore 12 * 12 = 144 donuts all together.

donuts with chocolate icing

144 \times  \frac{3}{8}  = 54

with white icing and sprinkles

144 \times \frac{1}{4}  = 36

donuts with pink icing

144 \times  \frac{1}{6}  = 24

Total donuts minus donuts with icing equal glazed donuts

144 - 54 - 36 - 24 = 30
