Solve for y. Round to the nearest whole degree.

68°

Step-by-step explanation:

From sin rule:

a / sin A = b / sin B = c / Sin C

b /sin B = c / Sin C

250 / sin y = 200 / sin 48

Cross multiply :

200 * siny = 250 * sin 48

Sin y = 185.78620 / 200

Sin y = 0.9289310

y = sin^-1(0.9289310)

y = 68.268790

y = 68°

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

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
