Answer:

  30°, 60°

Step-by-step explanation:

Let x represent the measure of the smaller angle in degrees. Then the larger unknown angle is 2x, and the sum of the angles in the triangle is 180°:

  x + 2x + 90° = 180° . . . the sum of the angles in the triangle

  3x = 90° . . . . . . . . . . . . subtract 90°, collect terms

  x = 30° . . . . . . . . . . . . . divide by 3; this is the smaller angle

  2x = 60° . . . . . . . . . . . .this is the larger angle

The two angles that are not the right angle are 30° and 60°.

Which of the following are solutions to 2x2 – 8x - 90? Select all that apply.
Bond [772]

Answer:

x=-5, x=9

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

2x^{2} -8x-90  

equate to zero

2x^{2} -8x-90=0  

so

2=-1\\b=-8\\c=-90

substitute in the formula

x=\frac{-(-8)\pm\sqrt{-8^{2}-4(2)(-90)}} {2(2)}

x=\frac{8\pm\sqrt{784}} {4}

x=\frac{8\pm28} {4}

x=\frac{8+28} {4}=9

x=\frac{8-28} {4}=-5

therefore

The solutions are x=-5, x=9
