To find the angle Q we can us the sin law so:

So we can solve for Q so:
Step-by-step explanation:
Let's call x the lenght and y the height. The perimeter will be:
p = 2x + 2y = 10
When the lenght is halved and the height double we'll have:
p = x + 4y = 14
These 2 equations form a system of equations2 that can be solved and give as result:
y = 3
x = 2
Answer:
0.375
Step-by-step explanation:
510 male out of a total of 1360
510/1360 = 0.375
The answer would be -84.
