4 * 10 = 40
5 * 10 = 50
6 * 10 = 60
The side length of the original large triangle are 40 feet, 50 feet, and 60 feet.
Answer:
Y = 15sqrt(3)/4
Z = 15sqrt(3)/2
b = 45/4
Step-by-step explanation:
Sin(60) =Z/15
sqrt(3)/2 = Z/15
Z = 15sqrt(3)/2
Sin(30) = Y/Z
½ = Y/Z
Y = ½(15sqrt(3))/2 = 15sqrt(3)/4
Cos(30) = b/Z
sqrt(3)/2 = b/Z
b = 15sqrt(3)/2 × sqrt(3)/2
b = 45/4
sqrt is square root/radical
No, you would only need to multiply 16 by 5 once
Step-by-step explanation:
15,729 = 10 000 + 5 000 + 700 + 20 + 9
= (1 x 10000) + (5 x 1000) + (7 x 100) + (2 x 10) + (9 x 1)
We can also write it like this :
(1 x 10⁴) + (5 x 10³) + (7 x 10²) + (2 x 10¹) + (9 x 10⁰)
