Answer:
2 mintues
Step-by-step explanation:
yes due to prisims am know to be very very small then that will to take around two minutes! glad myself can helped you are :)
The last one is not necessarily true
Answer:
3.9581139448
Step-by-step explanation:
8 ÷ 3 + 13
8 ÷ 3 = 2.66666667
2.66666667 + 13 = 15.6666666
square root of 15.6666666 is 3.9581139448
Answer:
45°
Step-by-step explanation:
the sum of angles in a triangle is equal 180°
we have been given that one angle equals yo 90° and the other equals to 45°
let "?" be the unknown angle
====> 180° = 90° + 45° +?
? = 180° - (90° + 45°)
? = 180° - 135°
? = 45°
1. You can divide the triangle shown in the figure attached in two right triangles with the length MR=8√3 and RO=<span>8√3
</span>
2. Let's choose one of the triangles and then we must apply the <span>Pythagorean Theorem, as below:
</span>
h²=a²+ b² ⇒ a=√ <span>h²-b²</span>
<span>
h: hypotenuse (the opposite side of the right angle and the longest side of the triangle</span><span>).
</span><span> a and b: legs (the sides that form the right angle).
</span><span>
3. </span>We want to find one of the legs (The height NR), so<span> we have:
</span><span>
h²=a² + b²
</span><span> a²=h²-b²
</span> a=√ <span>h²-b²
</span> a=√((16√3)²-(8√3 )<span>²)
</span> a=NR=<span>8√3
Then, the answer is: The height of the triangle is NR=</span>8√3 units<span>
