Tip - for finding the surface area of a triangle put two of them together so it forms a square find the area of that square and divide it by 2
The isometric transformation transform the an image to another exactly with the same shape & same size:
The most known isometric transformation are:
Translation (slide the image)
Reflection (flip the image around an axis
Rotation (turn the image)
Answer:
A and B
Step-by-step explanation:
i plugged them all into my graphing calc.
-10=20
1=20
-2= -28
20=1160
-2= -28
-1= -16
Answer:
The measure of a = b = 116 degrees
Step-by-step explanation:
Here, we have value of angles to calculate.
If a and b are both supplementary to c, what this means is that when we add either a or b to c, we get 180
Hence; Mathematically;
a + c = 180 and b + c = 180
What we have here is that a and b must be equal since they are both supplementary to the same angle value
Now, we are told further in the question that the measure of angle a is 12 less than 2 times the measure of c;
Mathematically, this means that;
a = 2c - 12
So we now want to find the measure of b
Let’s substitute for a
2c -12 + c = 180
3c -12 = 180
3c = 180 + 12
3c =192
c = 192/3
c = 64
Thus; a = 2c - 12 = 2(64) -12 = 128 -12 = 116
