You can find a common denominator using the two denominators multiples.
Answer:
sine 23 = x/21
Multiply both sides by 21
21 x sine 23 = x
Now, use a calculator and find the answer of the 21 times the sine of 23:
x = -17.7706284876
Answer:
si =25%*p
rate =term=t
from si= ptr/100
term = rate = 5

Answer:
x=2.5,y=8.75
Step-by-step explanation:
∵△ABC~△ADE
∴![\frac{AC}{AE} =\frac{AB}{AD} \\\frac{8}{10} =\frac{10}{10+x} \\10+x=12.5\\x=2.5\\\\\frac{AC}{AE} =\frac{BC}{DE} \\\frac{8}{10} =\frac{7}{y} \\8y=70\\y=8,75](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BAE%7D%20%3D%5Cfrac%7BAB%7D%7BAD%7D%20%5C%5C%5Cfrac%7B8%7D%7B10%7D%20%3D%5Cfrac%7B10%7D%7B10%2Bx%7D%20%5C%5C10%2Bx%3D12.5%5C%5Cx%3D2.5%5C%5C%5C%5C%5Cfrac%7BAC%7D%7BAE%7D%20%3D%5Cfrac%7BBC%7D%7BDE%7D%20%5C%5C%5Cfrac%7B8%7D%7B10%7D%20%3D%5Cfrac%7B7%7D%7By%7D%20%5C%5C8y%3D70%5C%5Cy%3D8%2C75)
