Answer:
The angles are 110, 110 and 140
Step-by-step explanation:
Let the equal angles be x.
So we have angles x, x and another third one
Now, the other third angle is 30 degrees larger than x, this means that the other third angle is 30 + x
Since they are angles at a point, adding the three together will make or give 360.
Thus,
x + x + x + 30 = 360
3x + 30 = 360
3x = 360-30
3x = 330
x = 330/3
x = 110
So the other third angle is 110 + 30 = 140
So the angles are 110, 110 and 140
Symmetry is the same as the one side of the graph but it is fliped on the X-axis
The diagonals of a rectangle are equal and bisect each other.
NQ= 2×5 =10
Using Pythagoras theoram,
PQ²+NP²=NQ²
4²+ NP²= 10²
NP²= 100-16
NP²= 84
NP =√84
<h3>
NP=2√21 = 9.2</h3>
Answer:
B. 12 square ft C. 63 square ft
Step-by-step explanation:
Marlena places a square rug on her living room floor, which is also a square.
Now if a square rug is placed in her room, the area of the floor will definitely be the area if the square rug..
And area of a square it = length ²
The result will give s a perfect square for an integer number.
A. 9 square ft = perfect square
B. 12 square ft = not perfect square
C. 63 square ft =not perfect square
D. 81 square ft= perfect square
So the ones that are not perfect squares Is the answer to the question
It is 54524.32.
Hope it helps
