Answer:
cos(x) = 0.6
Step-by-step explanation:
First, we need to find UQ.
UQ = UP·cos(y°) = UP·√(1 -sin²(y°)) = (26 cm)√(1 -25/169) = (26 cm)(12/13)
UQ = 24 cm
Then TQ is ...
TQ = 1/3UQ = 1/3(24 cm) = 8 cm
And cos(x°) is ...
cos(x°) = √(1 -sin²(x)) = √(1 -64/100)
cos(x°) = 6/10 = 3/5
cos(x°) = 3/5 = 0.6
Answer:
12.7
Step-by-step explanation:
you have to turn 4/5 into a decimal then subtract that from 13.50
Answer: 3 + n / 6 is less than -2
Explanation:
It’s an inequality:
Quotient: division
Sum: addition
A number: the variable, n
the 3th choice because it does not add up to 180, it actually adds up to something greater
The answer is A because 2time 2 is 4-2 =2 and then 120times 2 =240
