Answer:
B
Step-by-step explanation:
Supplementary angles sum to 180°, hence
3x + 9 + 2x + 2 = 180, that is
5x + 11 = 180 ( subtract 11 from both sides )
5x = 169 ( divide both sides by 5 )
x = 33.8
Hence the smaller angle has a measure of
2x + 2 = (2 × 33.8) + 2 = 67.6 + 2 = 69.6° → B
Romeo Whigh is 40m.
P=a*b,
a=60m, b=wight(w), P=2400m^2
w=?
Change known size in P=a*b
2400=60*w
w=2400/60
w=40m
the numbers are 31 and 14
since the larger number is 17 more than the smaller number,
larger number= x
smaller number= x-17
x-17+x=45
2x=45+17
2x=62
x=31
x-17=31-17
