suppose a triangle with angles measuring 30° , 35° and 115° is translated 1 unit left and 1 unit up on a coordinate grid Which would be the measure of an angle of the triangle

b) 35°

Step-by-step explanation:

The complete question is described below:

Suppose a triangle with angles measuring 30°, 35°, and 115º is translated 1 unit left and 1 unit up on a coordinate grid.

Which would be the measure of an angle of the resulting triangle?

a) 25°

b) 35°

c) 55°

d) 65°

From Linear Algebra we define the translation by the following expression:

(1)

Where:

- Original point, dimensionless.

- Translated point, dimensionless.

- Translation vector, dimensionless.

According to the statement, every point of the given triangle uses the following operation:

Hence, internal angles after translation conserve its initial values and the right answer is B.

yes

step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
