Find the measure of the indicated angle

Answers

Answer:

? = 110

Step-by-step explanation:

We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.

All angles of a triangle always adds up to 180

Add all the known angles 25 + 45 = 70

Than subtract 180 - 70 = 110

The answer for the indicated angle is 110 degrees

A parallelogram is formed by the points A (2, 4), B (6, 3), C (0, 0), and D (4, 1). What transformation could have occurred in order for A’ to be (3, 6)? A. Dilation of 150% B. Reflection across the axis y=5 C. Rotation of 90° about the origin D.Translation following the rule (x+2,y+1)

Answers

Answer:

c please give me brainliest

Step-by-step explanation:

The dilation of 150% from A(2, 4) to A'(3, 6). Therefore, option A is the correct answer.

Given that, a parallelogram is formed by the points A (2, 4), B (6, 3), C (0, 0), and D (4, 1).

What is the transformation?

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

The coordinates of the point A' is (3, 6)

Now, 150% of (2, 4) is 0.15 × 2 = 3 and 0.15 × 4 = 6

So, its dilation of 150% from A(2, 4) to A'(3, 6)

The dilation of 150% from A(2, 4) to A'(3, 6). Therefore, option A is the correct answer.
