18 - 7x = -20.52.5 = 7xx = 5/14 (c)
Answer:
137
Step-by-step explanation:
sum of angle in a circle = 360°
105 + 118 + x = 360
223 + x = 360
x = 360 - 223
x = 137
H equals 30 because 3 times 6 is 18 so 5 times 6 is 30
Answer:
cos 45 degree = A/H
cos 45 degree = 2 square root 2 / x
x = 2 square root 2 / cos 45 degree
x = 4
Sin 45 degree = O/H
Sin 45 degree = y/ 4
4 x Sin 45 degree = y
y = 2.83
or
we could use tan
tan 45 degree = O/A
tan 45 degree = y / 2 square root 2
2 square root 2 x tan 45 degree = y
y = 2.83
i hope this would elp a little bit.
Faucet one fills up

of the bathtub in one minute and faucet two fills up

of the bathtub in one minute. If both are one then they will fill up

So, 1/6 of the bathtub in one minute.
