Answer:
huh I would help but what the question?
Step-by-step explanation:
4x-7+37
add 7 to both sides
4x=44
divide by 4 on both sides
x=11
12(3+1)
12(4)
The number 12 times the number 4 is 48
It depends on whether you have "Perpendicular" or "base"
If you have perpendicular then, you can use the formula:
sin Ф = P / H
If you have base then, you can use the formula:
cos Ф = B/ H
Hope this helps!
