Answer:
c = 75 in
Step-by-step explanation:
The hypotenuse of a right triangle is found by the Pythagorean theorem:
<em>a² + b² = c²</em> (a and b are the legs, c is the hypotenuse)
Plug in: <em>45² + 60² = c²</em>
Square + square root: √(2025 + 3600) = c
Add: √5625 = c
Square root: 75 in = c (no negatives because we are finding distance)
Answer:
267.3
Step-by-step explanation:
area of a regular polygon =
(perimeter * apothem)/2
perimeter: 9 * 6.6 = 59.4
area: 59.4 * 9 = 534.6
534.6/2 = 267.3
area = 267.3
Here we have to use the theorem tht exterior angle is the sum of non adjacent interior angles. That is ,
z = x+y
And the values of x,y and z are given in terms of n. On substituting these values for x,y and z, we will get
151-5n = 4n-18+n+9
Combining like terms of the right side
151-5n = 5n -9
Moving 5n to the right side and 9 to the left side,
151+9 = 5n+5n
160=10n
Dividing both sides by 10
n = 16
Now we need to find the value of z when n =16. SO we substitute the value of n in z, that is
z =151-5(16) =151-80 = 71 degree .
So the correct option is A
Tan x + 1 = 0
tan x = -1
x = -π/4 + nπ ( n ∈ Z )
