One triangle has angles that measures 45 degrees and 83 degrees. Another triangle has angles that measure 45 degrees and 42 degrees Are the triangles similar? How do you know?

The two triangles are not similar

Step-by-step explanation:

Similar triangles have equal corresponding angles and proportion sides

Ex: If Δ ABC is similar to ΔXYZ, then

In the given question

∵ One triangle has angles that measure 45° and 83°

→ Find the measure of the 3rd angle

∵ The sum of the measures of the angles of a triangle is 180°

∴ The measure of the 3rd angle = 180° - 45° - 83°

∴ The measure of the 3rd angle = 52°

∴ The measures of the angles of this triangle are 45°, 83°, 52°

∵ Another triangle has angles that measure 45° and 42°

→ Find the measure of the 3rd angle

∴ The measure of the 3rd angle = 180° - 45° - 42°

∴ The measure of the 3rd angle = 93°

∴ The measures of the angles of this triangle are 45°, 93°, 42°

∵ The two triangles have different measures of 2 angles

→ That means their corresponding angles are not equal

∴ The two triangles are not similar

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
