Answer:

Step-by-step explanation:

Angles on a straight line add up to 180 so:

180-110 = 70

As this is an isosceles triangle,

y must be 70.

We know y is 70 and there are 2y and one x. A triangle also adds up to 180.

This means:

2y+x = 180

2(70)+x = 180

140+x = 180

x = 40

x = 40 y = 70

John shifted the decimal point of a number twice to the left to obtain a new number. The difference between the new number and t

NikAS [45]

Step-by-step explanation:

From a, the original number is 100x the new number.

So,if the new number is 1unit --> the original is 100x 1unit --> 100units

Add the two numbers together --> 1unit + 100units --> 101 units

We also know that the difference between the two numbers is 136.62

So 100units - 1unit --> 136.62

99units -> 136.62

1unit --> 1.38

101units --> 139.38
