Answer:
81
Step-by-step explanation:
9 x 9 = 81
So, 81 is the perfect square.
The values for x and y are respectively given as
This is further explained below.
<h3>What is the values for
x and y ?</h3>
Generally, the equation for secent is mathematically given as

Therefore

80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90

Answer:
27,050
Step-by-step explanation:
Thousand is three zeroes, so we start with 27,000
Hundred is two zeroes, so we add 300
Ones have no zeroes, so we add 5
27,305
but then this is times 10 which adds another zero, so our final result is
27,050
Answer:
c=3
Step-by-step explanation:
4c+12-2c=5c-3 1. combine like terms
2c+12=5c-3 2. -5c on both sides
-3c+12=3 3. -12 on both sides
-3c=-9 4. /-3 on both sides
c=3
The answer is A,D and E because they all have the same shape and size therefore they’re congruent.
