Yes that statement is correct because 12 is half of 24 and 2 is half of 4
Answer :
67.5 degrees
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
The sum of the measures of the angles of all triangles is 180 degrees.
Hence, the equation is
x + x + 45 = 180
Solve the equation for x
2x + 45 = 180
2x = 180 - 45
2x = 135
x = 67.5
Therefore, measure of other two angles are 67.5 degrees.
x = -15
Step-by-step explanation:

Collect like terms and simplify

Cross multiply

Well, this is absolute value, so as a mixed fraction you would have to times the denominator to the whole number, and then add the answer of that to the numerator (2 x 2 x 1). After that, you should get a whole number as an answer, but make it as a fraction. (put the whole number you got on top of the denominator before (2) to make it a fraction). Then, again, since it's absolute value, then it into a negative. Hope this helps and hope it not confusing!!
She done better at the 2nd test because she only got 4 wrong but on the first test she got 6 wrong.
