Answer:

Step-by-step explanation:

Given that in a right triangle, angles are 45 45 90

A 45 – 45 – 90 degree triangle (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of. Note that it's the shape of half a square, cut along the square's diagonal, and that it's also an isosceles triangle (both legs have the same length).

The hypotenuse measures 24 inches.

Since the other two angles are equal, we find that two legs would be equal

Let each leg = x

Then apply Pythagorean theorem to get x^2+x^2 = 24^2\\x=12\sqrt{2}

Thus we get

each leg of the right triangle = 12√2

Answer:

12\sqrt{2}\ in

Step-by-step explanation:

we know that

A 45\°-45\°-90\° right triangle has two equal legs

Let

x-----> the length side of the leg of the triangle

y------> the length side of the hypotenuse

sin(45\°)=cos(45\°)=\frac{\sqrt{2}}{2}

cos(45\°)=\frac{x}{y}

so

\frac{x}{y}=\frac{\sqrt{2}}{2}

in this problem we have

y=24\ in

substitute the value of y and solve for x

\frac{x}{24}=\frac{\sqrt{2}}{2}

x=24\frac{\sqrt{2}}{2}

x=12\sqrt{2}\ in

Answer:

d= 71518 kilometers

Explanation:

A diameter is twice the radius. Here, we can use the formula d=2r (d=diameter r=radius)

If we substitute the formula, we have

d=2(35795)

After multiplying:

d=71518 kilometers

Help....!! I need to solve this simultaneous equation y=x-2 and y=3x+5 With working out if possible please....
Blababa [14]

Step-by-step explanation:

Y= x - 2. Y = 3x + 5

Putting value of y

x - 2 = 3x + 5

-2 - 5 = 3x - x

-7 = 2x

-7/2 = x

Putting value of x

Y = 3(-7/2) + 5

Y = - 10.5 + 5

Y = - 5.5
