The angles in a triangle are such that one is 128° more than the smallest angle, while the third angle is two times as large as the smallest angle. find the measure all three angles.

Let x degrees be the measure of the smallest angle. Then, since the 3 angles in a triangle add up to 180 degrees:-

x + x + 128 + 2x = 180

4x = 180 - 128 = 52

x = 13 degrees

The measure of the 3 angles is 13, 26 and 141 degrees (answer)

step-by-step explanation:

the areas of two similar triangles are 18 cm2 and 8 cm2. one of the sides of the first triangle is 4.5 cm. what is the length of the corresponding side of the other triangle?

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
