Answer:

given: circle is tangent to one another

every circle is tangent to the side of 90 degree triangle ABC

radius of large circle= 12cm

radius of small circle= 3cm

to find : the area of triangle

start: first we should know the formula of triangle

  1. that is : 1/2× base × height
  2. area: 12 ab sin,
  3. area: 12 bc sin A
  4. area: 12 ca sin B

so the answer will be 486

this will be your answer

how are you unnie?

ANSWER:

The area of the triangle is [tex]1344 sq.cms[/tex].

Step-by-step explanation:

Given: Circles are tangent to one another.

             Each circle is a tangent to the ABC triangle.

             Larger circle radius [tex]12cms[/tex]

              Smaller circle radius [tex]3cms[/tex]

To find The area of the triangle.

Solution:

  • [tex]CAB = 2Arcsin3/5[/tex]
  • [tex]\frac{12}{AD} = \frac{3}{4}[/tex]
  • [tex]AD = 16[/tex]
  • AB [tex]= 28[/tex]
  • Now [tex]\frac{28}{AC} = cos 2 Arcsin\frac{3}{5}[/tex]
  • AC [tex]= 100[/tex]
  • CB [tex]\sqrt{100^{2} - 28^{2} }[/tex]
  • CB [tex]= 96[/tex]
  • Area of triangle [tex]= \frac{1}{2}[/tex] × L× B

                                   [tex]= \frac{1}{2}[/tex] ×[tex]96[/tex] ×[tex]28[/tex]

                                   [tex]= 1344 sq.cms[/tex]

  • Therefore the area of the triangle is [tex]1344 sq cms[/tex].
