In which triangle is the measure of the unknown angle, x, equal to the value of sin^-1[5/8.3]

2nd triangle from left

Step-by-step explanation:

sin⁻¹ (5/8.3)       sin x = 5/8.3

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
