Answer:
x=20°
2.
x=27°
Step-by-step explanation:
sin(x+20)=cos (2x+10)
=sin (90-(2x+10))
so x+20=90-(2x+10)
x+20+2x+10=90
3x=90-30
3x=60
x=60/3=20
2.
2x+14+x-5=90
3x+9=90
3x=90-9=81
x=81/3=27
Remainder of 6099 Divided by 7? The quotient (integer division) of 6099/7 equals 871; the remainder (“left over”) is 2.
Answer:

Answer:
h = V/y^2
Step-by-step explanation:
The volume of a right pyramid is given by the expression = Area of base × height.
Area of base = Area of square at the base
= y × y = y^2.
Now, we substitute these values:
V = y^2 × height
height = V/y^2
