5-3+10+137 10 and 137 are your numbers hope this helped
First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
Answer:
see below
Step-by-step explanation:
Order of operations is parenthesis, exponents, multiplication, division, addition, subtraction.
since there are no exponents in this problem the next step is -2(2.2)
Simplify the previous step and you get -4.4
final answer is -7.6 - 4.4 = -12
Answer:
are not and does not
Step-by-step explanation:
Answer:
h = 6
Step-by-step explanation:
We need to use Pythagorean theorem.
h² + 8² = 10²
h² = 100 - 64 = 36
h = 6
