The pair of 'vertical' angles at point 'Z' that are inside the triangles are equal.
Call me crazy, but I have a hunch:
Unless I miss my guess, there's a choice-(D) down below the
cut-off bottom of the picture, and that choice is "SAS similarity".
If I'm right, then that's your answer.
If I'm wrong, then you can delete my answer, and I'll mail back your 5 points.
Answer:
27cm²
Step-by-step explanation:
Chop the irregular shape into two rectangles!
(I divided by the inner corner next to the 5cm mark across to the side with no label at all on the left)
6x2=12 (longer rectangle)
5x3=15 (shorter rectangle)
12+15=27cm²
I hope this helps! :)
Answer:
hypotenuse=h
h = 1 + 1,5
h= 2,5
h²= catheto²+catheto²
2,5² = 1,5² + x²
x²= 2,5² - 1,5²
x²= 6,25 - 2,25
x²=4
now you have to do the square root of 4 which is 2 (2×2 = 4)
x= 2
