The sum of the angle measured in a triangle is 180°.two angle of a triangle measures 20° and 50°.what did is the measure of the third angle

110 Degrees

Step-by-step explanation:

The sum is when different numbers are added.

When all angles are added it adds up to 180 Degrees for any triangle.

Triangles have three sides and two are given as 50 Degrees and 20 Degrees.

There is one angle remaining.

50 Degrees + 20 Degrees = 70 Degrees

Therefore, the last angle must be 110 Degrees. (180-70)

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
