Answer:

x = 28°

y = 23°

Step-by-step explanation:

5y - 4 + 3y = 180

solve for y

8y = 184

y = 23

3y and 2x + 13 are equal

solve for x now that we know y is 23.

3(23) = 2x + 13

69 = 2x + 13

56 = 2x

28 = x

Answer:

y=23 x=28

Step-by-step explanation:

5y-4 + 3y =180⁰

8y-4=180

8y=184

y=23

3y=2x+13

69=2x+13

-13 -13

56=2x

28=x

Hope this is helpful. good luck

Simplify 6/6^1/4 rational exponents

White raven [17]

Answer:

we conclude that:

$\frac{6}{6^{\frac{1}{4}}}=6^{\frac{3}{4}}$

Step-by-step explanation:

Given

The expression is

$\frac{6}{6^{\frac{1}{4}}}$

To determine

Simplify the expression

Simplifying the expression

$\frac{6}{6^{\frac{1}{4}}}$

Apply the exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$\frac{6}{6^{\frac{1}{4}}}=6^{1-\frac{1}{4}}$

Subtract the numbers: $1-\frac{1}{4}=\frac{3}{4}$

$=6^{\frac{3}{4}}$

Therefore, we conclude that:

$\frac{6}{6^{\frac{1}{4}}}=6^{\frac{3}{4}}$

three trigonometric functions for a given angle are shown below csc theta = 13/12, sec theta = -13/5, cot theta = -5/12 what are

goldenfox [79]

We have that
csc ∅=13/12
sec ∅=-13/5
cot ∅=-5/12

we know that
csc ∅=1/sin ∅
sin ∅=1/ csc ∅------> sin ∅=12/13

sec ∅=-13/5
sec ∅=1/cos ∅
cos ∅=1/sec ∅------> cos ∅=-5/13

sin ∅ is positive and cos ∅ is negative
so
∅ belong to the II quadrant

therefore
the coordinates of point (x,y) on the terminal ray of angle theta are
x=-5
y=12

the answer is
point (-5,12)
