Answer:
4
Step-by-step explanation:
You need to find XYW
<xYW = <XYZ - <WYZ
<XYW = 128 - 85
<XYW = 43
12x - 5 = 43 Add 5 to both sides
12x = 43 + 5
12x = 48 Divide by 12
x = 48/12
x = 4
Answer:
AB = 23.4 inches
Step-by-step explanation:
If the diameter of the wheel is 25 inches, we have that its radius is 25/2 = 12.5 inches.
If we draw a radius to the bottom of the wheel and a radius to point A, we have a triangle where we can use Pythagoras' formula:
(see image attached for better understanding)
r^2 = (r-8.1)^2 + (AB/2)^2
12.5^2 = 4.4^2 + AB^2/4
156.25 = 19.36 + AB^2/4
AB^2/4 = 136.89
AB^2 = 547.56
AB = 23.4 inches
Answer:
23
Step-by-step explanation:
first term(a)= 2
difference (d) = 1.5
it's an arithmetic progression.
the formula for nth term is a+(n-1)d
n= 15
putting in the formula i get,
t15= 23
This is an EQUATION, because it has a left side, a right side, and an = sign separating the two.
An EXPRESSION does not has "sides" and no = sign.
