Consruct right triangle ABC with a hypotenuse, AC of length 17, and a long leg, AB, of length x. Angle B is the right angle. The measure of angle A is 31 degrees. Solve for the approximate value of x. Reread the description to make sure your diagram is correct. Do your work on lined paper and check it carefully. Make sure your calculator is in degree mode.

x = 14.57184411

rounded nearest thousandth: x = 14.572

Step-by-step explanation:

(using sine)

sin(59) = x/17

sin(59) = 0.8571673007

=> (rounded) 0.857 = x/17

multiply 17 on both sides

=> x = 14.57184411 or 14.572

no

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
