In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AB=4 and BC=3, Find AH, CH and BH.
IRISSAK [1]

Answer:

  • AH = 3.2
  • CH = 1.8
  • BH = 2.4

Step-by-step explanation:  

It can be convenient to compute the length of the hypotenuse of this triangle (AC). The Pythagorean theorem tells you ...

   AC^2 = AB^2 + CB^2

   AC^2 = 4^2 + 3^2 = 16 + 9 = 25

   AC = √25 = 5  

The altitude divides ∆ABC into similar triangles ∆AHB and ∆BHC. The scale factor for ∆AHB is ...

  scale factor ∆ABC to ∆AHB = AB/AC = 4/5 = 0.8  

And the scale factor to ∆BHC is ...  

  scale factor ∆ABC to ∆BHC = BC/AC = 3/5 = 0.6  

Then the side AH is 0.8·AB = 0.8·4 = 3.2

And the side CH is 0.6·BC = 0.6·3 = 1.8  

These two side lengths should add to the length AC = 5, and they do.  

The remaining side BH can be found from either scale factor:    

  BH = AB·0.6 = BC·0.8 = 4·0.6 = 3·0.8 = 2.4

_____  

The sides of interest are ...  

  AH = 3.2

  CH = 1.8

  BH = 2.4

A right triangle has leg lengths of 7 inches and 24 inches.
SSSSS [86.1K]

Answer:

The length of the hypotenuse = 25 inches

Step-by-step explanation:

A right triangle has leg lengths of 7 inches and 24 inches.

Given

  • a = 7
  • b = 24

<u><em>Pythagorean Theorem</em></u>

For a right-angled triangle with sides 'a' and 'b', the hypotenuse 'c' is

defined as:

c=\sqrt{a^2+b^2}

  • a=7 inches
  • b=24 icnhes

so substituting the values

c=\sqrt{7^2+24^2}

c=25 inches

Thus, the length of the hypotenuse = 25 inches
