0,55
Step-by-step explanation:
Answer:
87.407
Step-by-step explanation:
circumference = 2*pie*r
= 2*pie*17
=106.8/2
=53.4
53.4+(17*2)
=87.4
If c is the hypotenuse, we have

If instead b is the hypothenuse, you have

Answer:
Step-by-step explanation:
3x + 4 + 8x + 4 = 140 degree (sum of two interior opposite angle is equal to the exterior angle formed)
11x + 8 = 140
x = 140 - 8
x = 132 /11
x = 12
angle S = 3x + 4
=3*12 + 4
=36 + 4
=40 degree
89 + 5x - 7 = 14x + 1
82 + 5x = 14x + 1
82 - 1 = 14x - 5x
81 = 9x
81/9 = x
9 = x
angle H = 5x - 7
=5*9 - 7
=45 - 7
=38 degree
Here it is
67^2 = 67*67 = 4489
