Aneli [31]

Answer:

80° , 100°, 80°

Step-by-step explanation:

∠ 1 and ∠ 2 form a straight line and sum to 180° , then

2x + 40 + 2y + 40 = 180

2x + 2y + 80 = 180 ( subtract 80 from both sides )

2x + 2y = 100 → (1)

∠ 1 and ∠ 3 are vertical angles and are congruent , then

2x + 40 = x + 2y ( subtract x from both sides )

x + 40 = 2y ( subtract 40 from both sides )

x = 2y - 40 → (2)

Substitute x = 2y - 40 into (1)

2(2y - 40) + 2y = 100

4y - 80 + 2y = 100

6y - 80 = 100 ( add 80 to both sides )

6y = 180 ( divide both sides by 6 )

y = 30

Substitute y = 30 into (2)

x = 2(30) - 40 = 60 - 40 = 20

Thus x = 20 and y = 30

Then

∠ 1 = 2x + 40 = 2(20) + 40 = 40 + 40 = 80°

∠ 2 = 2y + 40 = 2(30) + 40 = 60 + 40 = 100°

∠3 = x + 2y = 20 + 2(30) = 20 + 60 = 80°

Which expression can be simplified to find the slope of the trend line in the scatterplot? On a coordinate plane, a line goes th
Goryan [66]

Answer:

(A)\dfrac{24-79}{12-2}

Step-by-step explanation:

Given the trend line which goes through (2, 79) and (12, 24).

Slope, m=\dfrac{y_2-y_1}{x_2-x_1} \\x_1=2, y_1=79,x_2=12, y_2=24\\$Therefore$:\\\\m=\dfrac{24-79}{12-2}

The equation which can be simplified to find the slope of the trend line in the scatterplot is \dfrac{24-79}{12-2}

The correct option is A.
