Answer:
x = 65.4
The answer is 65.4 degrees.
Step-by-step explanation:
You can use either sine, cosine, or tangent to find the measure of angle x, but since the lengths of the adjacent leg and the hypotenuse are already given, cosine will be the easiest to use. The adjacent leg is 5 units long, and the hypotenuse is 12 units long.
Remember, cos(x) = adjacent / hypotenuse.
cos(x) = 5/12
( ) both sides
(cos(x)) = (5/12)
Simplify ((cos(x)) ⇒ x)
x = (5/12)
Use calculator (make sure it is in degrees, not radians)
x = 65.37568165...
Round to the nearest tenth
x = 65.4

Answer:
Step-by-step explanation:
20 times pop. of Panama = 20×(4×10⁶) = 80×10⁶ = 8×10⁷
Population of Thailand = 7×10⁷ < 8×10⁷
pop of Thailand is less than 20 times pop of Panama.
For part 1 you would say the expression is:
I-3 because an expression does not have an equal sign and ingrid swam 3 laps less than holly
For Part 2, you would substitute 25 into l, so it would be 25-3 which equals 22
Hope this helps.
Hi there!
Reduced means "to simplify".
66/42=1 4/7.
66÷6=11 and 42÷6=7.
Therefore, 11/7=1 4/7.
So, 66/42 reduced is 1 4/7.
Hoped I helped. :)
