an obtuse angle
Step-by-step explanation:
obtuse angles measure from 91° to 179°
Answer:
see explanation
Step-by-step explanation:
differentiate using the power rule.
( a
) = na
, thus
(x² - x + 3 ) = 2x - 1
x = 5 → 2(5) - 1 = 10 - 1 = 9
To find the value of x for minimum , equate
to zero
2x - 1 = 0 , then
2x = 1 and
x = 
X= 9 is the answer to this question
Answer is 18
use the formula a^2 +b^2=c^2
