Answer:

m<R ≈ 22.62°

Step-by-step explanation:

Reference angle = R

Side opposite to R = 5 cm

Adjacent side length = 12 cm

Thus, applying TOA, we have:

Tan R = opp/adj

Tan R = 5/12

R = tan^{-1}(5/12)

R ≈ 22.62° (nearest hundredth)

Answer:

The result for this equation is $x = -5$ .

Step-by-step explanation:

-Solve the equation:

$3(4x-10)=2(3x-30)$

-Use Distributive Property:

$3(4x-10)=2(3x-30)$

$12x - 30=6x - 60$

-Subtract 6x and from 12x :

$12x - 30 -6x=6x -6x - 60$

$6x - 30=-60$

-Add both sides by 30:

$6x - 30 +30=-60 +30$

$6x =-30$

-Then, you divide both sides by 6:

$\frac{6x}{6}=\frac{-30}{6}$

$x = -5$

So, therefore the answer is $x = -5$ .

Answer:

11x-8

Step-by-step explanation:

First distribute the 3 and 2. (Only in the parenthesis!):

3(x-2)+2(4x-1)

3x-6+8x-2

Combine like terms:

3x+8x=11x

-6-2=-8

So the answer is:

11x-8
