Answer:
JKL=BCA
Step-by-step explanation:
Equilateral triangle mean every sides and angles are equal
so the measure of angles is 60 degrees
given that has an altitude of 15 m so this mean that
sin 60 = altitude / hypotenuse
sqrt3 /2 = 15/hyp.
hyp. = 15/(sqrt3 /2)
hyp. = 30/sqrt3 = 30sqrt3 / 3 = 10sqrt3
so in this way ve got that a side length is equal 10sqrt3 and the perimeter
P = 3*10sqrt3
P = 30sqrt3 m so the 3rd choice is right,correct sure
hope helped
Answer:
multiplicative inverse
Step-by-step explanation:
A number that is multiplied by it's multiplicative inverse equals one.
A multiplicative inverse is also called a reciprocal.
Example:
1/7 is 7's multiplicative inverse.
Answer:
It is 91% more likely that the tree was atmost 500 yards from the river.
<h3>Step-by-step explanation:</h3>
We are given with distance and height of 100 young trees near a river.
From that table, in total there are 55 trees which grow more than 3 ft during the year.
And among those 55 trees, 50 trees are atmost 50 yards from river.
Hence it is ≈91% more likely that the tree was atmost 50 yards from the river.
