We have to factorize the given expression.

The given expression can be write as

Taking out common value

Now, taking common factor out

Hence, the expression in factorize form is given by

Option D is true.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
