If m<2 =3x + 14 and m<7 =5x -60 then find the measure of angle 3
r-ruslan [8.4K]

Answer:

∠ 3 = 55°

Step-by-step explanation:

∠ 2 and ∠ 7 are corresponding angles and are congruent, then

5x - 60 = 3x + 14 ( subtract 3x from both sides )

2x - 60 = 14 ( add 60 to both sides )

2x = 74 ( divide both sides by 2 )

x = 37

∠ 2 = 3x + 14 = 3(37) + 14 = 111 + 14 = 125°

∠ 2 and ∠ 3 are adjacent angles on a straight line and sum to 180° , so

125° + ∠ 3 = 180° ( subtract 125° from both sides )

∠ 3 = 55°

Ok so the rectangle is 12x6 which is 72. The entire top part is 18 which means the other triangle side is 6. 6x6 = 36 so 72+36 is 108

Simplify the expression. What classification describes the resulting polynomial? (3x^2-11x-4)-(2x^2-x-6)
Gnoma [55]

The expression can be simplified to a polynomial of degree 2.

x^2 - 10x + 2

<h3>How to simplify the expression?</h3>

Here we have the expression:

(3x^2 -11x - 4) - (2x^2 - x - 6)

We can directly simplify this by taking the variable as common factor:

(3 - 2)*x^2 + (-11 + 1)*x + (-4 + 6)\\\\x^2 - 10x + 2

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.
