Answer:

<A = 35 degrees

Step-by-step explanation:

<A = x

<B = 2x

<C = 2x + 5

X + 2x + 2x + 5 = 180 degrees

5x + 5 = 180

5x = 180 -5

x = 175/5

x = 35

Solve for x: 3x − 2 &gt; 5x + 10. (5 points)<br> 1) x &gt; 6<br><br> 2) x −6
san4es73 [151]

Answer:

x

Step-by-step explanation:

3x-2>5x+10

Add 2 to both sides

3x-2+2>5x+10+2

Simplify

3x>5x+12

Subtract 5x from both sides

3x-5x>5x+12-5x

Simplify

-2x>12

Multiply both sides by -1 (reverse the inequality)

(-2x)(-1)

Simplify

2x

Divide both sides by 2

\frac{2x}{2}

Divide the numbers: \frac{2}{2} =1

=x

Divide the numbers: \frac{-12}{2}

Apply fraction rule: \frac{-a}{b} =-\frac{a}{b}

=\frac{12}{2}

Divide the numbers: \frac{12}{2} =6

1.Find the dot product of the two given vectors, u=(1,6) and v=(-5,-2) 2. Find the dot product of v=-7i+4j and w=-6i+5j
Svet_ta [14]
The dot product of the two vectors will be given as follows:
v*w=(-7i+4j)*(-6i+5j)
=(-7*(-6))i+(4*5)j
=-42i+20j

Hence the answer is:
v*w=(-42i+20j)

Find the value of the trigonometric ratio: tan X.
serious [3.7K]

Answer:

The value of the trigonometric-ratio:

  • Tan X = 24 / 7

Step-by-step explanation:

Given the angle X

It is clear that:

  • The opposite of the angle X = 48
  • The adjacent to the angle X = 14

We know that the trigonometric-ratio of Tan X is defined as

Tan X = Opposite / Adjacent

substituting Opposite = 48, and Adjacent = 14

Tan X = 48/14

Tan X = 24 / 7

Therefore, the value of the trigonometric-ratio:

  • Tan X = 24 / 7
