1 answer:
Gennadij [26K]3 years ago

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio on right triangle KJL

and the exact value sin30° = \frac{1}{2}

sin30° = \frac{opposite}{hypotenuse} = \frac{JL}{KL} = \frac{JL}{8\sqrt{2} } = \frac{1}{2} ( cross- multiply )

2JL = 8\sqrt{2} ( divide both sides by 2 )

JL = 4\sqrt{2}

---------------------------------------------------------

Using the sine ratio in right triangle JLM

and the exact value sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenude} = \frac{LM}{JL} = \frac{x}{4\sqrt{2} } = \frac{1}{\sqrt{2} } ( cross- multiply )

x × \sqrt{2} = 4\sqrt{2} ( divide both sides by \sqrt{2}

x = 4

Find the distance between A (2,6) and N (5, 10). Round<br> To the nearest tenth
Svetllana [295]

Answer:

5.0 units

Step-by-step explanation:

The distance between two points can be expressed in formula of:

\displaystyle{d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}}

Determine:

  • \displaystyle{(x_2,y_2)} is (5,10).
  • \displaystyle{(x_1,y_1)} is (2,6).

Therefore, substitute in the formula to find distance:

\displaystyle{d = \sqrt{\left(5-2\right)^2+\left(10-6\right)^2}}\\\\\displaystyle{d = \sqrt{3^2+4^2}}\\\\\displaystyle{d = \sqrt{9+16}}\\\\\displaystyle{d = \sqrt{25}}\\\\\displaystyle{d = 5}

Therefore, the distance between two points is 5.0 units.

Mia climbs 5/8 of the height of the rock wall. Lee climbs 4/5 of Mia's distance. What fraction of the wall does Lee climb?
Lina20 [59]
The answer is 7/40. To solve, you have to find the LCM (least common denominator) for 5/8 and 4/5. 5/8= 25/40 and 4/5= 32/40. Subtract and you get 7/40. That is your answer.
