If you subtract 6 from 33 youll end up with 27 and therefore 27 plus 6 equals 33

Answer:

Substitute 27 for the variable, n. Then simplify by adding 27 and 6. Adding 27 + 6 = 33. So you have 33 = 33, which is a true statement. 27 is a solution of the equation.

What are the ratios for sin A and cos A? The triangle is not drawn to scale.
dalvyx [7]

Answer:

SinA = \frac{84}{85}  and  CosA=\frac{13}{85}

Step-by-step explanation:

The ratios of sine and cos are defined as follows:

Sin A = \frac{Opposite}{Hypotenuse} , and

CosA = \frac{Adjacent}{Hypotenuse}

The hypotenuse is always the side opposite of the 90 degree angle (for the given triangle, the hypotenuse is 85)

Since we are looking at the angle A, the opposite side with respect to A would be the side length of 84. That leaves the side 13 as the adjacent side.

Thus, we can now write:

Sin A = \frac{Opposite}{Hypotenuse}\\SinA = \frac{84}{85}

CosA = \frac{Adjacent}{Hypotenuse}\\CosA=\frac{13}{85}

The correct answer is  the first answer choice.

18+9+15x is still the same as 15x+____

so 27+15x is =15x+27

Identify the angle relationship, write an equation and Solve for x. ​
irakobra [83]

Answer:

2x-6+x+x=180

4x-6=180

4x=180+6

4x=186

x=\frac{186}{4}=46,5°

Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
