my is cutting a triangle shaped baseball pennant banner out of felt. She starts by cutting a base 6 inches long and two angles that each measures 75°. What will the third angle measure?
Responses
A 30°
B 20°
C 25°
D 50°
To find the third angle of the baseball pennant banner, we can use the fact that the sum of the angles in a triangle is always 180°.
The two angles that are given each measure 75°, so the sum of these angles is:
75° + 75° = 150°
To find the third angle, we can subtract this sum from 180°:
180° - 150° = 30°
Therefore, the third angle of the baseball pennant banner will measure 30°.
The answer is A) 30°.
