Answer: 19%
Step-by-step explanation:
You take 17 times 2.5 which you get 42.5 which is so you know how much the battery has charged. You then take the 61.5 minus 42.5 and which is 19
you a protracter to measure the points.
15*9=135
135+7=142
142 squared = 20,164
or you can put (7+15*9) the power of 2 and you will get the same answer
The 2 triangles are congruent therefore
9x-1 = 10x-10
x= 9
so 80* 2 = 160
angle cad measures 160 degrees
