Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Answer:
neg 13333333333/50000000000
Step-by-step explanation:
Yes,it can be proved to be congruent,as:
AB=AD (given)
AC=AC (given)
Since AB = AD,it is an isosceles △
Thus,BC=CD(properties of isos.△)
Therefore,ΔCAB ≅ ΔDAC (SSS)
The answer is Yes;ΔCAB ≅ ΔDAC
Hope it helps!
2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
