Answer:
The first choice ( Refection over x axis)
Step-by-step explanation:
Take a mirror and put it on the x-axis and imagine the triangle which be create
I hope that is useful for you :)
Unlike positives, with negatives, the larger a number is, the smaller it is.
Example :
4 > 2
-4 < -2
so -1.8 is GREATER then -2.1
here is a tip :
picture ur number line....plot -2.1....any number to the right is greater and any number to the left is less...and since -1.8 is to the right of -2.1, it is greater then -2.1
Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
If a is directly proportional to b, we have the relationship to be:
When a = 25, b = 35. Therefore, we can calculate the value of k as follows:
Therefore, the relationship is given to be:
When a = 40, we can calculate the value of b to be:
The value of b is 56.
