Answer:
Each base angle is 81°
Step-by-step explanation:
A pennant is in the shape of an isosceles triangle and the vertex angle is 18°.
An iscosceles triangle has two equal sides and two equal angles.
So assuming the base angles measure b° each;
b° + b° + 18° = 180° (angles in a triangle add up to 180°)
2b° = 180° - 18° = 162°
b = 162° ÷ 2 = 81°
So each base angle is 81°
A) 25% of males preferred playing sports.
Explanation) .25 is the same is 25%.
B) 25% of the people surveyed preferred reading a book.
Explanation) You have to add up how many males and females rather
to read a book. It's .10 + .15 = 25%.
C) 70 females were surveyed out of 200 people.
Explanation) Add up .15 + .5 + .15 to get .35. Put .35 multiplied by 200 to get 70.
