Answer:
The answer to your question is: length = 10.4 units
Step-by-step explanation:
Data
It's a right triangle with angles 30°- 60°- 90°
I'll solve this exercise with the function sine and cosine
a) sin 60 = long leg / hypotenuse
long leg = hypotenuse x sin 60
long leg = 12 x 0.87
lon leg = 10.4 units
b) cos 30 = long leg / hypotenuse
long leg = hypotenuse x cos 30
long leg = 12 x 0.87
long leg = 10.4 units
Answer:
width: 13 Length: 15
Step-by-step explanation:
Let length be x
width is x-2
perimeter is 56
P= 2(l+b)
56= 2(x +x-2)
56/2 = 2x - 2
28 + 2 =2x
30= 2x
15 =x
15-2+13
length =15
width = 13
Answer:
The first one is arithmetic and the second one is geometric.
Step-by-step explanation:
Arithmetic is basically like skip counting. 1 time 7 is 7, two times 7 is 14, etc...
Geometric is anything all the numbers added to get a total of 360. The next two terms for the first one is 42 and 49.
