Answer:
so 2x+3x+130=180
so 5x+130=180
5x=50
so 2x =20
3x which is angle a is equal to 30 degree
45/26=1.7307692307692307692307692307692...
≈1.7308
100*1.7308=173.08
The unknown number is approximately 173.08.
Answer:
Rule = 759375(1/15)^(n-1)
Where n represent the number of term
Step-by-step explanation:
a5= ar^4= 15
a6= ar^5= 1
ar^4=15... Equation 1
ar^5=1.... Equation 2
Dividing equation 2 by equation 1
r= 1/15
For the value of a
ar^5=1
a(1/15)^5= 1
a(1/759375)= 1
a= 759375
Rule = 759375(1/15)^(n-1)
Where n represent the number of term
Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)
X = 3
Combine like terms: -4 + -5 = -9
-9 + 6x + -3x = 0
Combine like terms: 6x + -3x = 3x
-9 + 3x =0
Solving -9 + 3x = 0
Solving for variable ‘x’
Moving all terms containing my x to the left, all other terms to the right
Add ‘9’ to each side of the equation -9 + 9 + 3x = 0 + 9
Combine like terms: -9 + 9 = 0
0+3x=0+9
3x = 0 + 9
Combine like terms: 0 + 9 = 9
3x = 9
Divide each side by ‘3’.
X = 3
