Answer:

45°

Step-by-step explanation:

Corresponding angles are equal. ∠4 and ∠2 are equal.

$x+30=2x+15$

Add -x and -15 on both sides of the equation.

$30-15=2x-x$

$15=1x$

∠4 = x+30

Put x as 15 in the equation.

$(15)+30$

$=45$

What polynomial, when divided by 7y^3, yields 3y^2-4y+7 as a quotient?

weqwewe [10]

Answer: 21y^5-28y^4+49y^3

If the remainder isn't necessarily zero, we add C_1y^2+C_2y+C_3, which covers all possible remainders when dividing by a polynomial with leading term in y^3.

Step-by-step explanation:

(3y^2-4y+7)(7y^3) =

21y^5-28y^4+49y^3
