Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

x+2x+21=180

Combine like terms:

3x+21=180

Subtract 21 from both sides:

3x=159

Divide both sides by 3:

x=53

Therefore, the value of x is 53 degrees.

Solve for T <br> Please Need Help
lara [203]

Answer:

T = \frac{6b+4}{R}

Step-by-step explanation:

B=\frac{RT-4}{6}

6B=RT-4  (times 6 on both sides)

6B+4=RT (add 4 to both sides)

\frac{6B+4}{R} = T  (divide R on both sides)

thus

T = \frac{6b+4}{R}

Find the value of x. A. 53–√ m B. 241−−√ m C. 6 m D. 6+35–√ m
dalvyx [7]

Answer:

<h2>x = 2√41 m</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

a² = b² + c²

where a is the hypotenuse

From the question x is the hypotenuse

So we have

<h2>{x}^{2}  =  {8}^{2}  +  {10}^{2}</h2><h2 /><h2>{x}^{2}  = 64 + 100</h2><h2 /><h2>{x}^{2}  = 164</h2>

Find the square root of both sides

We have the final answer as

<h3>x = 2√41 m</h3>

Hope this helps you
