The sum of the interior angles of a triangle add up to $180^{\circ}$ . Therefore, an equiangular triangle will have each of its angles equal to $60^{\circ}}$ . We can then set up the following equation:

$2x+8=60, \\2x=52, \\x=\fbox{$26$}$ .

Solve A=1/2bh for b when A=126 and h=18

Slav-nsk [51]

Answer:14

Step-by-step explanation:First, you can plug in the numbers, so the equation would look like 126=1/2b(18). Since theres 1/2, 1/2 of 18 is 9, so it would be 126=9b. 126/9=14

If the coefficient of determination is 0.233, what percentage of the variation in the data about the regression line is explaine

ddd [48]

We need the coefficient of determination definition

The coefficient of determination (R²) is a number between 0 and 1 that measures how well a statistical model predicts an outcome. You can interpret the R² as the proportion of variation in the dependent variable that is predicted by the statistical model

So if we have a coefficient of determination of 0.233 we multiply by 100 to get the percentage

Answer: 23.3%
