Answer:

x = 60°

Step-by-step explanation:

AOB    Center: O      AB: diameter

arc ADB = 180°

arc DB = 180 - arc AD = 80°

x = 1/2 x ( arc DB + arc AC) = 1/2 x (80 + 40) = 60°

Write the faction ration for each of the following.<br> If m
Aleksandr-060686 [28]

Answer:

\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0

Step-by-step explanation:

In any right triangle, the following is true:

The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)

The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus,

\text{3. }\\\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1},

\text{4. }\tan 68^{\circ}=\frac{GI}{2},\\GI=2\tan68^{\circ}=4.95017370683\approx \boxed{5.0}

Howard’s uncle gave him $885 for his tenth birthday. The money was invested in a savings account with interest compounded at 12%
Stella [2.4K]
Principal Amount = P = $885
Amount Accumulated = A = $3500
Interest rate = r = 12% = 0.12
Compounding period in a year = n = 2
Time in years = t = ?

The formula for compounding is:

A=P(1+ \frac{r}{n})^{t*n}

Using the values, we get:

3500=885(1+ \frac{0.12}{2})^{2*t} \\  \\ &#10; \frac{3500}{885} =(1.06)^{2t} \\  \\ &#10;log(\frac{3500}{885})=log((1.06)^{2t}) \\  \\ &#10;log(\frac{3500}{885})=2tlog(1.06) \\  \\ &#10;t= \frac{log(\frac{3500}{885})}{2log(1.06)}  \\  \\  \\ &#10;t=11.80

This means, it will take him 11.8 or approximately 12 years
