Answer:
130
Step-by-step explanation:
ABC = 180 - 120 = 60
ACB = 180 - 70 - 60 = 50
ACD = 180 - 50 = 130
I hope I've helped you.
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:
$6,400
Step-by-step explanation:
1) 20% of 32,000 goes to housing!
This can be written as 0.2 times 32,000
The value of: 0.2 x 32,000 equals 6,400!
That would be your answer ($6,400)
