Answer:
Step-by-step explanation:
7.50a + 2.50c = 1945
a + c = 364
Use -2.50 for 2nd equation
7.50a + 2.50c = 1945
-2.50a - 2.5oc = -910
5a = 1035
a = 207 adult tickets were sold
207 + c = 1945
c = 1738 child's tickets were sold
Answer:
115°
Step-by-step explanation:
The above shape is a quadrilateral.
A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.
The sum of interior angles of a Quadrilateral is 360°
Therefore,
115 + 65 + 65 + m = 360
245 + m = 360
m = 360 - 245
m = 115°
Therefore, m< B = 115°
