Problem 17
Focus on one of the triangles. It has legs of 8 and 15. Use the pythagorean theorem to find the hypotenuse is 17.
Basically you're solving for c in a^2+b^2 = c^2. Use a = 8 and b = 15.
The diameter is 17 and the circumference is
C = pi*d = pi*17 = 17pi
<h3>Answer:
17pi</h3>

Problem 18
This figure has four faces, so this is a tetrahedron. The "tetra" is greek that translates to "four".
Another possible name for this figure is triangular pyramid because we have a pyramid with a triangular base.
<h3>Answer: Triangular pyramid or tetrahedron</h3>
Answer:
30 degree
Step-by-step explanation:
sum of the interior angles of a hexagon=720degree
one angle of the hexagon=720/6=120degree
one angle of the rhombus=90 degree
therefore, x=120-90=30
Answer:
Since it is a linear function, it is a directly proportional function
Step-by-step explanation:
i looked it up
A: 2 if u don't know then the first option .
(2x + 10)(x - 9)
2x(x - 9) + 10(x - 9)
2x(x) - 2x(9) + 10(x) - 10(9)
2x² - 18x + 10x - 90
2x² - 8x - 90
