One angle of a right triangle measures 31° what is the measure of the other angle

59°

Step-by-step explanation:

A triangle adds up to 180°. A right triangle has a 90° angle.

1. Set up the equation

90 + 31 + x = 180

2. Simplify

121 + x = 180

3. Solve for x by subtracting 121 from both sides

x = 59

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
