Pythagoras' Theorem only works with right angle triangles.
A makes a right angles triangle because:
√3² + 4² = 5
However B doesn't because:
√7² + 8² = 10.631 (which is not 9)
Nor does C because:
√3² + 9² = √90 (which is not √95)
So the answer is A
Answer: %2.1352
(Rounded =%2.1)
Step-by-step explanation:
5.5/5.62=0.978648
1.0 - 0.978648= 0.021352
(Move the decimal over 2 places to the right to convert to percent)
002.1352
%2.1352
(Rounded =%2.1)
Answer:
find the square root of 64
x=8
Step-by-step explanation:
Answer:
X axis (x,y) -> (x,-y)
Step-by-step explanation:
A = 133; b = 31; c = 82; d = 64.
Opposite angles in an inscribed quadrilateral are supplementary; this means that d + 116 = 180. Subtracting 116 from both sides, we have d = 64.
By the same theorem, c + 98 = 180; subtracting 98 from both sides, we have c = 82.
Inscribed angles are equal to 1/2 the measure of the intercepted arc. Using this, we have
116 = 1/2(a+99)
Multiplying both sides by 2, we have
232 = a+99
Subtract 99 from both sides:
232 - 99 = a + 99 - 99
133 = a
We also have that
82 = 1/2(133+b)
Multiplying both sides by 2, we have:
164 = 133 + b
Subtract 133 from both sides:
164 - 133 = 133 + b - 133
31 = b
