How do I find an angle to a 90 degree triangle with only the length of the sides

22.6°

Step-by-step explanation:

the cosines rule :

cos x = (24²+26²-10²)/2(24)(26)

= (576+676-100)/1248

= 1152/1248

= 0.923

so, x = cos`¹ 0.923 = 22.6°

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
