Answer:
Lets mark the unmarked angle as angle A and the base of the building as BC
We can use tan to find this
tan=opposite/adjacent
by knowing the 2 interior angles we can calculate the measure of A sicne the interior angles of any triangle add up to 180
52+90+A=180
142+a=180
38=a
tan(38)=BC/300
300 tan(38)=bc
using a calculator we see that bc=234.385689 or 234meters rounded
Step-by-step explanation:
A and b are legs, c is hypotenuse

Step-by-step explanation:
The vertex order has been reversed, so a reflection is involved. The direction of the short side has been changed by 90°, so a rotation is potentially involved. Depending on the precise rotation and/or reflections, translation may be involved.
One potential set of transformations is ...
- rotate 90° CW about the origin
- translate left 1 and down 3
- reflect across the y-axis
Another potential set of transformations (shown below) is ...
- reflect across the line x+y=1
- translate down 4
