Answer:

42

Step-by-step explanation:

there are 180° in a triangle. so all three angles must add up to this.

54 + x + 2x = 180

x + 2x = 126

3x = 126

x = 42

The country recreation department cleared a 3/4 mile long walking trail in Washington Park. There will be a small sign every 1/1
dem82 [27]

We are given " The country recreation department cleared a 3/4 mile long walking trail in Washington Park."

Therefore total distance = 3/4 miles.

"There will be a small sign every 1/12 mile along the trail, including at the beginning and end of the trail. "

Distance of small sign = 1/12 mile.

We need to find the number of signs in 3/4 miles each of 1/12 miles.

<em>In order to find the number of signs, we need to divide total distance by distance of a small sign.</em>

3/4  ÷ 1/12

= 3/4 × 12/1 = 3 × 3

= 9 signs.

<h3>Therefore, 9 signs are needed.</h3>

Can someone Please help me on this math problem
sdas [7]

Answer:

  False

Step-by-step explanation:

Residuals are the measure of the error in the fit. The square of their sum gives no weight to the sign of the error, but gives greater weight to larger errors. The fit will be better when the error is <em>smaller</em>. In this scenario, Line B is a better fit.

The statement that Line A better fits the data is FALSE.
