For a complimentary pair of angles i.e a+b=90 degrees, then cos a= sin b
so;
3x+2=4x-10
2+10=4x-3x
x=12.0
Answer:
24 square inches
Step-by-step explanation:
We are given Image of letter E with height of 12 and width of 7
Inside space of height of 5 and width of 6
Initially calculate the area of rectangle ABKL = length *width = 12*7= 84 square inches
Now to get the area of given figure subtract the area of rectangle CDFE and HGJI from the rectangle ABKL
Area of CDEF = Area of HGJI because the length and width of the rectangles is same
Thus Area of CDEF = length *width =5*6 = 30 square inches
Thus the Area of HGJI = 30 square inches
Now subtract the area of both rectangles from the area of rectangle ABKL
⇒84-(30+30)
= 24 square inches .
Hence the area of given figure LETTER E = 24 square inches .
Answer:
Step-by-step explanation:
7.18/9 divide 9 and that would equal 2/1 so its 2
8.24/40 divide 8 and that would equal 3/5
9.7/21 divide 7 and that would equal 1/3
10.9/1 stays the same so its 9
