A right triangle has one angle that measures 13.7°. what is the measure of the other acute angle

One of the angles of a right triangle is always 90 degrees. we have another 13.7 degrees angle. so we can find the other acute angle
$180 - (13.7 + 90) = 180 - 103.7 \\ = 76.3$

Write an equation in which the quadratic expression 2x^2-2x-13 equals 0

torisob [31]

Answer:

x = 3 and -2 are the two solutions.

Step-by-step explanation:

2x^2 -2x -12 = 0

First factor out a 2

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0

2 = 0 x - 3 = 0 x + 2 = 0

2 does not equal zero so this is an extraneous solution

x - 3 = 0 so x = 3

x + 2 = 0 so x = -2
