\huge\boxed{45^\circ}

See the attached diagram.

Together, angles BDC and ADB form a right angle, which is 90 degrees.

The angles are split straight down the middle, meaning they're equal to each other. This means each one is equal to half of 90 degrees, which is 45 degrees.

7.1 as a fraction or mixed number in simplest form?
Andreas93 [3]

The simpliest form is 71/10, the fraction

Step-by-step explanation:

Since this isn't a really small (1/1000000000) or really big (like the radius of the earth) number you don't need the standard notation, so the fraction 71/10 is the simpliest because there is only a decimal, so it can be a fraction of ten.

I need help on this guys pls help me
STatiana [176]

Answer:

The answer is A

Step-by-step explanation:

The reason A is correct is because all of the other transformations change the size of the triangle, and A is the only answer that only reflects the image over the y axis without changing it, thus making it similar to the preimage
