47. The legs of a triangle measure 7 mm and 24 mm. What length hypotenuse makes the triangle a right triangle?

k0ka [10]

Answer:

Step-by-step explanation:

according to pythagorean

$7^{2} + 24^{2} =x^{2}$ (x>0)

=> $x^{2} =625$

=> $x=\sqrt{625}$ = 25

MArishka [77]

Answer:

The left side 5

The bottom 10

The slanted side 11

Step-by-step explanation:

To find the perimeter of the triangle, add up the side lengths

x+ 2x+1 + x+5 = 26

Combine like terms

4x+6 = 26

Subtract 6

4x+6-6 =26-6

4x=20

Divide by 4

4x/4 = 20/4

x=4

The left side x = 5

The bottom x+5 = 5+5 = 10

The slanted side = 2x+1 = 2*1 +1 = 10+1 =11

Given: ∆ABC –iso. ∆, m∠BAC = 120°

lidiya [134]

Answer: $P\triangle ADH = (a+b+\sqrt{a^2+b^2} )$ unit

Step-by-step explanation:

Since Here Δ ABC is a isosceles triangle.

Also, $AH\perp BC$ and $HD\perp AC$

Thus, ∠ ADH = 90°

That is, Δ ADH is the right angle triangle.

In which, AD = a unit and HD = b unit

And, By the definition of Pythagoras theorem,

$AH^2 = HD^2 + AD^2$

⇒ $AH^2 = a^2 +b^2$

⇒ $AH = \sqrt{a^2+b^2}$

Since, the perimeter of a triangle = sum of the all sides of the triangle.

Therefore, perimeter of ΔADH = AD + DH + AH

= $a + b + \sqrt{a^2+b^2}$ unit
