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:
9x - 36 = 10
Step-by-step explanation:
3/4 x - 3 = 5/6
The least common multiple of 4 and 6 is 12.
Multiply both sides of the equation by 12.
12 * (3/4 x - 3) = 12 * 5/6
12 * 3/4 x - 12 * 3 = 10
9x - 36 = 10
The new value would be $134.40; 1.12 times 120
Answer: (3,1)
Step-by-step explanation: You put y over x and then you simplify it like a fraction and put it back in the form of a coordinate point
