Fill in the missing reason in the proof a) definition of straight angles b) alternate interior angles are congruent c) supplementary angles sum up to 180° d) complementary angles sum up to 180° abc is a triangle given de ||ac given ∠ a = ∠abd alternate interior angles are congruent ∠ c = ∠cbe alternate interior angles are congruent ∠abd + ∠b + ∠cbe = 180° ? ∠a + ∠b + ∠c = 180° substitution

its A not C i got it wrong when i tried C

answer: entity is prob the answer

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
