Triangles abc, edc, and efg are similar triangles. the measures of the three interior angles of triangle efg are °, °, and °.

Step-by-step explanation:

We know by given that .

Similarities refers to proportional sides and congruent angles, so

, by corresponding elements.

Therefore,

By the same reason,

Then,

, by internal angles theorem.

Replacing values, we have

Therefore, the interior angles of triangle EFG are 30°, 50° and 100°.

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

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
