Answer:

B: 2,5

Step-by-step explanation:

Step One: We must assume this is rotating in a clockwise rotation since it is not -90 and there is no mention of it otherwise.

Step Two: To do this problem, you need to know the 90-degree rotation formula: (b, -a). This means that we make the x-coordinate negative and then switch spots with the x and y coordinates.

Step Three: By following this formula, we would make -2 negative, which makes it positive. Currently, the equation is (5, 2). Now, we need to finish the formula by swapping places: (2,5). That is the answer.

In the triangle below, find the measurements of the unknown angles.

Soloha48 [4]

Answer:

E) 35°, 70°.

Step-by-step explanation:

Given that the triangle has angles of a°, 2a° and 75°.

A triangle is a polygon shape that has three sides and three angles. The sum of angles in a triangle is 180°. There are different types of triangles such as scalene triangle, isosceles triangle, equilateral triangle e.t.c.

In the triangle:

a + 2a + 75 = 180° (sum of angles in a triangle)

3a + 75 = 180

adding -75 to both sides:

3a + 75 - 75 = 180 - 75

3a = 105

a = 105/3

a = 35°

Hence 2a = 2(35) = 70°

Therefore a = 35° and 2a = 70°
