Answer:
m∠B = 141°
Step-by-step explanation:
sides of polygon (n) = 7
sum of angles of polygon = {(n - 2) * 180°}
= {(7 -2)*180°}
= 5* 180°
= 900°
Now,
m∠B = 900° - 148° - 142° - 130° - 129° - 120° - 90°
m∠B = 141°
Answer:
Step-by-step explanation:
5a.) It starts with two at time one and increases by one each time
5b.) x+1
6.) Formula: (2/3)(x-1)+1, the fifth term would be (2/3)*(5-1)+1= 11/3
7a.) I will leave you to make the table. n+2 is wrong because it's increasing by 2 blocks each time
7b.) 2n+1
8a.) x²
8b.) just draw a 6x6
8c.) 12²=144
Answer:
42
Step-by-step explanation:
This time, you'll be doing SOH.
sin (x) = 39/59=0.66
then do sin^-1 (0.66)
x = 42 degrees (think this is correct I hope)
Answer:
2.16
Step-by-step explanation:
r = cost of ruler
p = cost of pencil
r = 2p
6r + 15p = 2.16
Substitute 2p in place of r in 2nd equation and solve for p
6(2p) + 15p = 2.16
12p + 15p = 2.16
27p = 2.16
