Answer:
450
Step-by-step explanation:
If the perimeter is 90 inches then each side must equal 30 inches. To find the area of a triangle you mulptiply the base by the height and divide by 2. The base is 30 and the height is 30. 30*30=900. 900/2=450.
The expression is no very clear.
It seems to be - x / 7 + 4 < 3x
If so, this is the solution.
1) 3x + x / 7 > 4
2) 21x + x > 28
3) 22x > 28
4) x > 28/22
5) x > 14/11
Answer: x > 14 / 11
Answer:
x = 2π3
Step-by-step explanation:
csc(x)csc(x) , x=πx=π
3x+2y+zx+y+z3x+2y+zx+y+z , x=2x=2 , y=3y=3 , z=1z=1
cot(3x)cot(3x) , x=2π3
Hope this helps :)
Answer:
I think the answer is 43
Step-by-step explanation:
Because b=83
The total value of triangle angles =180
So 54+83=137
180-137=43
