If the length of the shorter leg of a right triangle is 5 cm and the length of the hypotenuse is 8 cm, find the length of the lo
Brilliant_brown [7]

Answer:

The length of the longer leg is 6.24 cm.

Step-by-step explanation:

Here, the length of the hypotenuse  = 8 cm

The length of shorten leg ( Base) = 5 cm

Let us assume the length of longer leg (Perpendicular)   = k cm

Now, as the given triangle is a right angled triangle.

So, by the PYTHAGORAS THEOREM:

( Base)^2 + ( Perpendicular)^2  = ( Hypotenuse)^2\\\implies (5)^2  + (k)^2  = (8)^2\\\implies k^2  = 64 - 25  =  39\\\implies k^2  = 39\\k = \sqrt{(39)}  = \pm (6.24)

Now,as k is the length of the side, so it cannot be negative.

⇒   k  =  6.24 cm

Hence, the length of the longer leg is 6.24 cm.

If LMNO is a rectangle, and mMON = 30, what is the value of x?
sladkih [1.3K]

Answer:

The answer is the option E

120\°

Step-by-step explanation:

we know that

If LMNO is a rectangle

then

The triangle OCN is an isosceles triangle----> (C is the center of the rectangle)

so

m ------> the base's angles of the isosceles triangle

m -----> by vertical angles

Remember that the sum of the internal angles of a triangle must be equal to 180\°

therefore

2*30\°+x\°=180\°

solve for x

x=180\°-2*30\°=120\°
