2. according to the Pyphagorean theorem (in the smallest triangle):

answer: y=√55.
Combinatorial Enumeration. That whole class was a rollercoaster ride of mind-blowing generating functions to prove crazy things. The exam had ridiculous questions like 'count the number of cactus trees with n vertices such that etc etc etc' and you'd do three pages of terrible terrible sums and algebra. Then your final answer would be something beautiful like n/2 and you'd breath a sigh of relief and thank the math gods.
Answer:
11.4
Step-by-step explanation:
d² = 6² + 6² - 2(6)(6)cos145
d² = 130.9789472
d = 11.44460341
Answer:
105 maybe
Step-by-step explanation:
The area of a figure is the amount of space the figure occupies
The surface area of the figure is 34.8 square meters
<h3>How to determine the area of the shape</h3>
From the question, we have:
- The dimensions of the congruent squares are 3 m by 3 m
- The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 * Area of square + Area of parallelogram
This gives

Evaluate the products

Evaluate the sum

Hence, the surface area of the figure is 34.8 square meters
