Tan = opposite/hypotenuse
tan = 25/65
tan = 5/13
Answer:
0
Step-by-step explanation:
Sum means addition so:
-9 + 18/2
(18/2 = 9)
-9 + 9
0
Answer:
8
Step-by-step explanation:
<span>The smallest possible length of congruent sides of an acute isosceles triangle must be < than the length of congruent sides of the right isosceles triangle
so
</span>The sides of a right isosceles triangle are in proportion: √2/2:√2/2:1
if the longest side of an acute isosceles triangle is ----------- > 8 centimeters
then
the smallest possible length of one of the two congruent sides
is 8*√2/2- ---------->4√2=5.66=5.6
5.6<5.66------------- is ok
we know that the two smallest sides of a triangle have to add up to be longer than the longest side.
2x>8---------- > x>4
therefore the solution is the interval (4,5.6)
the smallest possible length rounded to the nearest tenth is 4.1
the answer is 4.1
