We know that the angles in a triangle are equal to 180.

39+57+x=180

96+x=180

x=84

Sum of the Interior angles of a triangle is equal to 180 degrees - x+57+39=180

Therefore, x=180-39-57

Hence, x=87 degrees

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

mariarad [96]

$x_{1}=1$
$x_{2}= 3$
$y_{1} =14$
$y_{2}=4$
$Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5$

answer: The student flipped the y values

Answer: 20

20 since you have to divide 100 by 5 which equals 20 since you have to use the inverse operation of multiplication which is division.

Hope this helps!

△ABC and △JKL have corresponding equal angles. Side length BC is twice the length of side KL. Which statement is true? A. △ABC a

lyudmila [28]

Answer:

A. △ABC and △JKL are similar.

Step-by-step explanation:

Since three angles of one triangle are congruent to three corresponding angles of the other triangle, the triangles are either congruent or similar. Since the side of one triangle is twice the length of the corresponding side of the other triangle, then the triangles are not congruent, but they are similar.

A. △ABC and △JKL are similar.
