Answer:
Step-by-step explanation:
2(2x +4) - 2x = x + 18
4x +8 -2x = x +18
2x -x = 18-8
X = 10
Put the value of x in both side
Left side *+*+*+*+*+
2 ( 2*10+4)-2*10
48-20 = 28
Right side +*+*+*+*+*
X + 18
10+ 18 = 28

ΔACD and ΔASR are the same so we can write a ratio:
x/4 = 10/5
x/4 = 2
x/4 * 4 = 2 * 4
x = 8
Since AS is equal to x, they are both the same.
Therefore, the answer is [ x = 8, AS = 8 ]
Best of Luck!
The common ratio is 2:1, or dividing by 2
For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
