Answer:

x = 3

Step-by-step explanation:

12 is the total length of the line segment.

Substitute x for 3

Then solve 3^2

3^2 = 9

Then add 3 and 9

3 + 9 = 12

This makes 3 the correct answer.

If the angles are represented in degrees, find both angles: \cos(3x+13)=\sin(2x+42) cos(3x+13)=sin(2x+42)

Sphinxa [80]

Answer:

cos34°

sin56°

Step-by-step explanation:

Sin(2x+42)= sin90-(3x+13)

Sin(2x+42) = sin(90-13-3x)

Sin(2x+42) = sin(77-3x)

2x + 42 = 77-3x

5x. = 35

X = 7

If x = 7

cos(3x+13) = cos((3*7)+13)

cos(3x+13) = cos(21+13)

cos(3x+13)= cos34

And

sin(2x+42) = sin((2*7)+42)

sin(2x+42)= sin (14+42)

sin(2x+42) = sin56

3. Which expression is equivalent to the expression shown below?

chubhunter [2.5K]

Answer:

option a

Step-by-step explanation:

we have:

7/2x-3(5x-1/2)

apply distributive property we have:

7/2x-3*5x-3*(-1/2)

7/2x-15x+3/2

7/2-15=-23/2

so we have:

-23/2x+3/2
