3x+14=2+5x-20
3x+14=5x-18
-5x -5x
-2x+14=-18
-14 -14
-2x=-32
Divide that -32 with -2
And the answer is x=16.
Answer:
angle a is 73 and angle c is 180-(73+73)=34
We know that
in the right triangle ACD
Applying the Pythagoras theorem
AC²=AD²+CD²------> AD²=AC²-CD²-----> AD²=5²-4²---> AD²=9----> AD=3
let
∅=angle CAD
tan ∅=4/3
in the right triangle CDB
the angle DCB is equal to ∅
tan ∅=DB/CD-------> DB=CD*tan ∅------> DB=4*(4/3)----> DB=16/3
AB=AD+DB-----> 3+16/3----> AB=25/3----> AB=8.33
the answer is
<span>b. 8.3</span>
Step-by-step explanation:
Let the number be x, then
15 less than a product of 2 and a number
