Angle P is 3 more than twice angle M. If the two angles are complementary, find the measure of the two angles.

kotegsom [21]

Answer:

29° and 61°

Step-by-step explanation:

Complementary angles sum up to 90°

Given

P + M = 90°
P = 2M + 3°

Substituting P in the first equation

2M + 3° + M = 90°
3M = 87°
M = 29°

Then

P = 90° - 29° = 61°

The sum of the roots of 3x 2 + 11x - 4 = 0 is -11/3 -4/3 11/3 4/3

givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$ .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

$3x^2+11x-4=0$ ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

$\frac{-b}{a}=-\frac{11}{3}$

The sum of roots is $-\frac{11}{3}$ .

Therefore the correct option is 1.
