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°

When you subtract and add what is in the parentheses you would get -15 so I’m guessing he didn’t go from left to right when working inside the parentheses but when you solve the whole problem out you would get the answer: -41.25 If I missed something or you need me to show the work just let me know but I hope this helps !

A total of 448 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students

olga55 [171]

Kid tickets = 3d

D = adult tickets

448 = (3 * d) + d

448 = 4d

448/4 = 112

112 = d

3 * d = 336

There are 336 kid tickets and 112 adult tickets sold.

Answer:

None of those options

Step-by-step explanation:

I just did the work myself and even ran it through a calculator but the correct answer isn't one of those options. Here's my work:

$-\frac{5}{6} =z+\frac{1}{8}\\-\frac{5}{8}-\frac{1}{8}=z\\-\frac{40}{48}-\frac{6}{48}=z\\-\frac{46}{48}=z\\-\frac{23}{24}$

I'd contact you teacher about that...it might be an error in their system (it's happened to me a few times before where the correct answer is marked as incorrect or isn't even an option)
