Answer:
x = 11/10
Step-by-step explanation:
5(2x-1)=6
Distribute
10x -5 = 6
Add 5 to each side
10x-5+5 = 6+5
10x = 11
Divide by 10
10x/10= 11/10
x = 11/10
Answer:
53.1°
Step-by-step explanation:
Let x represent the wangle of elevation from B to C
Reference angle = x
Opposite side to x = 16 - 4 = 12
Adjacent = 9
Apply trigonometric ratio to find x.
Thus:


(nearest tenth)
Angle of elevation from B to C = 53.1°
True because congruent means identical in form.
So all you need to do in order to find the sum is add so 185+66=251
Answer:
x=0
Step-by-step explanation:
combine like terms on both sides of the equal sign
-9+x= x-7
move similar terms to the same side
-2=0x
divide both sides by x
x=0
