Since l is parallel to m, the angle of 9x has to equal 153°:
9x = 153° Divide both sides by 9
x = 17°
Step-by-step explanation:
since we have at F a 90 degree angle, b is simply the difference between 90 and 33 degrees
b = 90 - 33 = 57 degrees.
and since all angles in a triangle must sum up to 180 degrees, this applies also to HFG. and we know 2 angles : H = 54 degrees, b = 57 degrees
a = 180 - 54 - 57 = 69 degrees
e is simply the counterpart of the 90 degree angle at F, as these 2 angles must sum up to 180 degrees again.
so, e = 180 - 90 = 90 degrees.
c is the complementary angle to 54, as for a pair of angles at a line intersection, these 2 angles must again sin up to 180 degrees
c = 180 - 54 = 126 degrees
and d is the third angle of EFG, where we know 2 angles, and again, the sum of all angles must be 180.
d = 180 - 90 - 69 = 21 degrees

2.
Multiply each term of first polynomial with each term of 2nd polynomial.
Multiply the numerical coefficient and add the powers of x.
3.
Multiply each term of first polynomial with each term of 2nd polynomial.
Multiply the numerical coefficient and add the powers of x.
Add or subtract like terms together.
The answer for multiplying polynomials:
69.99
20% off of 14.99 is 119.992 then -50 is 69.992 but we round to nearest cent and sence 2 is less than five we round down so jt is 69.99$
