Find what is x.
the total interior angle of the triangle is 180 degrees

you can use this formula (n-2)180, n is the number of sides of the shape
find what is x:
180-37-22=121
use the sin rule whereby,
(sin 121)/4.357=(sin 22)/a
(sin 121)a=( 4.356 ×(sin22) )
a= (4.356× sin22) /(sin 121)

type in the calculator to find what is a.

If the side length of a square pyramid is triple and the slant height is divided by 5 what would be the formula to find the modi
valentina_108 [34]
If the original side length is "s" and the original slant height is "h", the original surface area is
.. S = (base area) +(lateral area)
.. S = s² +(1/2)*(4s)*h
.. S = s(s +2h)

Now, if we make these replacements: s ⇒ 3s, h ⇒ h/5, we have
.. S' = (3s)(3s +2h/5)
.. S' = 9s² +(6/5)s*h . . . . . . . the formula for the modified area (in terms of original dimensions)

_____
Of course, in terms of the modified dimensions, the formula is the same:
.. S' = s'(s' +2h')
