Answer:

Step-by-step explanation:

\frac{8}{32}  =  \frac{4}{16}  =  \frac{2}{8}  =  \frac{1}{4}

\frac{27}{54}  =  \frac{9 }{18}  =  \frac{3}{6}  =  \frac{1}{2}

\frac{36}{24}  =  \frac{18}{12}  =  \frac{9}{6}  =  \frac{3}{2}

\frac{30}{60}  =  \frac{15}{30}  =  \frac{5}{10}  =  \frac{1}{2}

I hope this helps you



✔cos^2A+sin^2A=1


✔1-cos^2A=sin^2A

✔cos2A=cos^2A-sin^2A

✔sin2A=2.sinA.cosA


secA=1/cosA


tgA=sinA/cosA


sin^2A/1/cos^2A-sin^2A/cos^2A


sin^2A.cos^2A/cos2A

2.sin^2A.cos^2A/cos2A


sin2A.2.sin2A/cos2A


tg2A.2.sin2A

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer.
valentinak56 [21]

Answer:

1,225 miles = 77616000 inches

Step-by-step explanation:

It is asked to find the number of inches in 1,225 miles

Given

1 inch ≈ 1.578 × 10^-5 miles

Therefore, 1 mile  = 63360 inches

Therefore, 1,225 miles = 1225 x 63360 inches

                 1,225 miles = 77616000 inches

or               1,225 miles = 7.7 x 10^{7} inches

Therefore the final answer is

1,225 miles = 77616000 inches

or               1,225 miles = 7.7 x 10^{7} inches

zlopas [31]

Answer:

a= c/2

b= (c/2)×√3

side b is the side with the 60 degree angle.

side a is the side with the 30 degree angle.

using the theorem that the side with the 60 degree × 2 = length of side c and the side with the 60 degree × √3 = b.

I get the following equations shown above.
