No because it's a square it has to have 4 right angles.
A is the right one:
a. 3:4=9:12
3×3:4×3=9:12
Answer:
y = -1.71x + 6.42
Step-by-step explanation:
The gradient at any point on the curve is given by the expression;

At the point (2,3), the gradient of the curve will be:

The equation of this curve at this point can be given by:

Where 
Substituting these values into the given equation:

Answer:
the answer is 8
because 24 divided by 3 is 8
Hi there!
Let the second angle be represented by x. Now, just use the given information to write expressions for each angle.
Angle 1:
The question says that it is 10 degrees less than the second angle. Therefore, it can be represented by the expression x - 10.
Angle 2:
Represented by x.
Angle 3:
As said in the question, the third angle is 2 times the second angle. This gives us the expression 2 × x, giving us 2x.
Now, take all the expressions and add them up and make them equal to 180 degrees, according to the Triangle Sum Theorem.
x + 2x + x - 10 = 180
4x - 10 = 180
4x = 190
/4 /4
x = 47.5
Therefore, the angle measures are 47.5 degrees, 2(47.5) = 95, and 47.5 - 10 = 37.5 degrees. Hope this helped!
