21) 0.2800

22) 1.8750

23) 0.8000

Step-by-step explanation:

sin = opp/hyp

cos = adj/hyp

tan = opp/adj

19) sin Z = 40/50 = 0.8

20) sin C = 30/34 = 0.882352941

21) sin A = 7/25 = 0.28

22) tan X = 30/16 = 1.875

What is the product of 1 1/2 and -1 1/4?

Savatey [412]

positive number times negative number is negative number "(+)(-) = (-)".

$1\dfrac{1}{2}\cdot\left(-1\dfrac{1}{4}\right)=-\left(1\dfrac{1}{2}\cdot1\dfrac{1}{4}\right)$

we change the mixed numbers to the improper fractions

$=-\left(\dfrac{1\cdot2+1}{2}\cdot\dfrac{1\cdot4+1}{4}\right)=-\left(\dfrac{3}{2}\cdot\dfrac{5}{4}\right)=-\dfrac{3\cdot5}{2\cdot4}=-\dfrac{15}{8}=-1\dfrac{7}{8}$
