What is the measure of ∠E? Explain how you know.

The triangle in the middle is isosceles so the angles on the base are equal and together with angle f, add up to 180°.

e = 75°

75° + 75° + f = 180°

f = 180° - 150°

f = 30°

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
