Answer: smaller angle = 17°
The angle is a right angle so the total degree of the angle would be 90°
Step-by-step:
Equation:
(4x+1)+(x-1) = 90
5x = 90
X = 18
Smaller angle:
(X-1)
(18-1)
17°
Answer: the area for the square is 126.56cm²:
Sorry but I am depressed and I just need points for this but I’ll help you :)
<span>Answers:
V = (15-2x)(8-2x)x
V = 120x -46x²+ 4x³
V' = 120 -92x + 12x²
0 = 120 -92x + 12x²
x = (92±52)/24
x = 6 or 5/3
Pick x = 5/3
Volume = (15-2*5/3)(8-2*5/3)*5/3
= 90.74 inÂł
To justify x = 5/3 is the max
V" = -92 + 24x
V"(5/3) = -92 + 24(5/3) <0 negative.
Volume V(5/3) is max because the function is
concave down with V"<0.</span>
The experimental probability is 9/20 or 45%. Hope this helps!
