Murrr4er [49]

Answer:

∠GHE = 55°

Step-by-step explanation:

ABCD is a quadrilateral (4 sided figure). We know that the sum of the interior angles (4 angles) of a quadrilateral in 360°.

Thus, A + B + C + D = 360

<em>we know b = c = 90 and a = 125, thus we can find D.</em>

<em>125 + 90 + 90 + D = 360</em>

305 + D = 360

D = 360 - 305 = 55°

<u>Note:</u> since Quadrilateral ABCD is congruent to Quadrilateral EFGH, then the measure of D is equal to measure of H (Angle GHE). Thus

∠GHE = 55°

2nd answer choice is correct

Yes

remember that an odd power of a negative is negative
(-1)(-1)(-1)=(-1) tiat is negative
alsoo remember that ∛(ab)=(∛a)(∛b)

so
∛(-64)=(∛-1)(∛64)=(-1)(4)=-4
