4.5 speed is distance divided by time <span />
Answer: b
its a 3.5 degree angle it is b
i donk know Step-by-step explanation:
Using sin law;
sin A/ a = sinB/ b
where A = C or 90 degrees; a = 21
B = ? , b = 8
solving for b;
sin(90) / 21 = sin(B) / 8 ; B = 22.39 degrees
Total angle of triangle = 180
180 - 90 - 22.39 = x
x = 67.607 degrees
