Answer:

aₙ=23 - 8n

Step-by-step explanation:

15, 7, -1,....

AP with the first term of 15 and common difference -8

aₙ=a₁+(n-1)d= 15+(n-1)*(-8)= 15 -8n +8= 23 - 8n

aₙ=23 - 8n

To find the answer,we can set an equation adding up all the angles:

a°+2a°+2a°+a°=360°
6a°=360°
a°= 360°/6
a = 60

Therefore,the answer is 60.

Hope it helps!

Ms catall is using a compass to find her way out of the woods the compass has a radius of 4cm what is the compass’s area

S_A_V [24]

Answer:

50.24

Step-by-step explanation:

→To find a circle's (compass) area, you must use the following formula:

A = π $r^2$

→All you need to do is plug in 4 for the "r," (radius), and solve:

A = π $4^2$

A = π $(16)$

→When you multiply 16 by pi, we're going to use 3.14:

A = 3.14(16)

A = 50.24
