Hello!
3 out of 5 looks like this as a fraction:
3/5
We cannot divide this further as both the numerator and the denominator are odd numbers, so we must multiply to get an equivalent fraction:
3/5 = 6/10 = 60/100
3/5 is also equivalent to 0.2 as a decimal or 20% as a percentage.
Answer:
10
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
