Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Polygon ABCD is a parallelogram, and m∠ABC = 127°. The length of is 10 units, and the length of is 5 units.

The perimeter of the parallelogram is units, and m∠BCD is °

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

m∠a is 90°

m∠b is 40°

0.038
