I gave y'all the exact question, I have no idea where to start.

$\frac{(n-2)\cdot180}{n}\\\\
n=7\\
\frac{(7-2)\cdot180}{7}=\frac{5\cdot180}{7}\approx 128.6^{\circ}

In triangle abc, the measure of angle b is 32 degrees more than three times the measure of angle

Yuki888 [10]

Define x:
Let angle a be x.
angle a = x
angle b = 3x + 32
angle c = x + 58

Find x:
Angles in a triangle add up to 180°:
x + 3x + 32 + x + 58 = 180

Combine like terms:
5x + 90 = 180

Take away 90 from both sides:
5x = 90

Divide by 5 on both sides:
x = 18°

Find the angles:
angle a = x = 18°
angle b = 3x + 32 = 3(18) + 32 = 86°
angle c = x + 58 = 18 + 58 = 76°

Answer: The angles are 18°, 86° and 76°.

You go to the bakery with $20. You buy a small cake for 12.75. cookies cost .75 each. How many cookies can you buy ?

irakobra [83]

$20 - $12.75 = $7.25

$7.25 / $0.75 = 9.6

So you can buy C) 9.6 cookies.
