Answer:
86 cm
Step-by-step explanation:
parameter of the Pentagon
= the parameter of the square + the parameter of the
triangle
= 48 + 38
= 86
The formula for the triangular sequence is Xn=n(n+1)/2
So X25=25(25+1)/2=325
Answer:
Step-by-step explanation:
Given

Determine the line equation in slope intercept
The equation of a line in slope intercept is:
Where
So, becomes
X=Since you have an angle, a hypotenuse, and the opposite side, we can use:
sin(x)=opposite/hypotenuse
sin(60)=x/8 (cross multiply)
sin(60)*8=x
√3/2*8=x
x=8√3/2
x=4√3 so the answer is B
Hope this helps
Answer:
40
Step-by-step explanation:
