Answer:

The three angles of a triangles are 90° , 45°, 45°

∠A = 90° , ∠B = 45° and ∠C = 45°

Step-by-step explanation:

Explanation:-

Step(i):-

The sum of measures of three angles of any triangle is equal to 180°

Let A , B , C be the angles of the triangle.

∠A +∠B +∠C = 180°

Given data a triangle has angles measuring 2x°, x° and x°

2x°+ x° + x° = 180°

4x° = 180

x° = $\frac{180}{4} = 45$

x = 45°

Step (ii):-

Given data 2x = 2 × 45 = 90°

x = 45°

and x = 45°

The three angles of a triangles are 90° , 45°, 45°

∠A = 90° , ∠B = 45° and ∠C = 45°

Final answer:-

The three angles of a triangles are 90° , 45°, 45°

∠A = 90° , ∠B = 45° and ∠C = 45°

is it possible to store a 20 foot long pipe in a rectangular room that is 10 feet by 12 feet by 8 feet?

Anastaziya [24]

First we'll consider the floor size.
In a 10 by 12 room the longest pipe that will fit lying on the floor equals the hypotenuse of a 10 by 12 triangle:
hypotenuse² = 10² + 12²
hypotenuse² = 100 + 144
hypotenuse² = 244
hypotenuse = 15.62 feet

Now we have to consider the third dimension (height = 8 feet).
The two sides would be 15.62 and 8
hypotenuse² = 15.62² + 8²
hypotenuse² = 244 + 64 = 308
hypotenuse = 17.55
So, the longest pipe that would fit in that room would be 17.55 feet long.

Someone please help I hate probability :(

nikdorinn [45]

I think starting from the top it would go as follows

9/36, 27/36, 32/36 , 4/36

b.) 9/36

c.) I really don't remember how to do the "order doesn't matter" thing anymore, so idk. my best idea is for you to look up the formulas for permutation and combinations. I know it has to do with that

Evaluate each function. 1) f(x) = x2 + 4x; Find f(-7)

katrin [286]

Answer:

The answer is -77

Step-by-step explanation:

Ok, so assuming by x2 you mean x squared, I will solve this. So basically when you have a function, f(-7) would mean that you would have to replace all the x's in the equation with -7. So let's write that out. that would be f(-7) = -7^2 + (-7*4). So now according to PEMDAS, you would solve the exponent first, and -7^2 is equal to -49, because when you solve it you would do -(7^2), which is -(49), which is then -49. So now you have f(-7)= -49+ (4*-7). Solving for (4*-7), you get -28. This leaves you with -49 + (-28), which is -49 - 28. Simplifying that, you get the answer, which is -77.
