Answer:
x = 10
y = 11
Step-by-step explanation:
angle C is a right angle because AC = BC, so it is 90 degrees, meaning that 9x = 90. 90 divided by 9 is 10, so <em>x = 10</em>.
angle A = angle B, because AC = BC, so A and B are congruent. angle A measures 72 degrees, so angle B measures (8y-16) = 72.
(8y-16) = 72
+16 +16
8y = 88
divide by 8 on both sides
<em>y = 11</em>
Answer: first off the first is 240 2. is 320 in total so its the 2cnd one

Answer:
Step-by-step explanation:
Scientific notation is a quick way to represent a number using powers of base ten. This notation is used to be able to express very large or very small numbers very easily.
The numbers are written as a product:
a * 10ⁿ
where:
- a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
- n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it shifts to the left, negative if it shifts to the right.
Comparing what is equal to these two numbers when they are written in scientific notation you can see that the value of a is such that 1 ≤ a <10
Comparing what is different from these two numbers when they are written in scientific notation, you can see that the value of the exponent n in both numbers is different, one being positive, indicating that it is a very large number, and the other negative, indicating that it is It is a very small number that is between 0 and 1.
