What is the value of x? sin(x+22)°=cos(2x−7)°

1 answer:

5 0

Remember that $\sin(\theta) = \cos(90^\circ - \theta)$

Thus, we can solve for x.
x + 22 = 90 - (2x - 7)
x + 22 = 97 - 2x
3x + 22 = 97
3x = 75
x = 25

Write the rational number as a decimal. Show your work. 5/9 -3/8 -3/11.

Bad White [126]

I have memorized facts about fractions like these, so can tell you ...

$\dfrac{5}{9}=0.5\overline{5}\\\\-\dfrac{3}{8}=-3\times 0.125=-0.375\\\\-\dfrac{3}{11}=-0.27\overline{27}$

_____

A fraction with 9 as a denominator is a repeating 1-digit decimal with the decimal digit being the numerator of the fraction.

A fraction with 11 as a denominator is a repeating 2-digit decimal with the two digits being 9 times the numerator of the fraction.

1/8 = 0.125, so any multiple of 1/8 is that multiple of 0.125.
