Mathematics

Answer:

x=20

Step-by-step explanation:

This is a right triangle, so we can use the pythagorean theorem to help us find x.

The the theorem states that the sum of the legs squared is equal to the length of the hypotenuse squared.

Thus, our equation is:

x^2+48^2=52^2

Simplify.

x^2+2304=2704

Subtract 2304 from both sides.

x^2=400

Find the square root of both sides.

x=20

Answer:

x = 20

Step-by-step explanation:

We need to use Pythagoras theorem in this question. Pythagoras theorem states that a² + b² = c². This means that c² is hypotenuse (the angle opposite the right angle) but in this question we are given the length of the hypotenuse so we have to rearrange the equation,

→ a² + b² = c²

⇒ Substitute in the values

→ 48² + b² = 52²

⇒ Simplify it

→ 2304 + b² = 2704

⇒ Minus 2304 from both sides to isolate b²

→ b² = 400

⇒ Square root both sides to isolate b and find the value of x

→ b = 20

The length of x is 20

Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions
WITCHER [35]
Solve   <span>6x+4x-6=24+9x.  Combine all the x terms on one side and all the constants on the other:

10x-9x = 24+6, or x = 30.  ONE soution.


Solve   </span><span>4x+8=2x+7 +2x-20.  Combine all the x terms on one side and all the constants on the other:  4x - 2x - 2x = 7 - 20 - 8 =>   0 = -21

This is NEVER true, so   </span><span>4x+8=2x+7 +2x-20    has NO SOLUTION.

Please try solving equation B yourself.  Then I'd gladly comment on your work.</span>

a triangle has an area of 38.4cm.the height of the triangle is 12.8cm.what is the length of the base of the triangle​
Solnce55 [7]

Answer: 6  cm

Step-by-step explanation:

Use equation for area of triangle

A=a*h/2

a*h=2A

a=2A/h

where a  represents base of triangle

h represents height of triangle.

h=12.8 cm

A=38.4 cm²

a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm= 6 cm
