A) (x÷7)-10
B) 7x -10
C) (x-10)÷7
D) (x÷7)-10
A and D are the same
<h3>
Answer: 19.1</h3>
====================================================
Work Shown:
tan(angle) = opposite/adjacent
tan(C) = AB/BC
tan(theta) = x/BC
tan(23) = (8.1)/BC
BC*tan(23) = 8.1
BC = (8.1)/tan(23)
BC = 19.0824041631723
BC = 19.1
In this case, rounding to 3 sig figs means we round to the nearest tenth.
Make sure your calculator is in degree mode.
Assuming second equation is 6x+8y=44
so first divide 2nd eqation by 2 to make it eqaier
3x+4y=22
sub 6x+4 for y
3x+4(6x+4)=22
3x+24x+16=22
minus 16 both sides
27x=6
divide both sides by 27
x=2/9
sub back
y=6x+4
y=6(2/9)+4
y=12/9+4 (4=36/4)
y=48/9
