In which triangle is the measure of the unknown angle, x, equal to the value of sin–1? image for option 1 image for option 2 image for option 3 image for option 4

Its option B  trust me It is right

Step-by-step explanation:

yep, no doubt about it. its option B

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
