The measure of angle A is 15°, and the length of side

dangina [55]

Answer:

Part 1) $AB=30.9\ units$

Part 2) $AC=29.9\ units$

Step-by-step explanation:

The picture of the question in the attached figure

Part 1

Find the length side AB

we know that

$sin(A)=\frac{BC}{AB}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(15^o)=\frac{8}{AB}$

solve for AB

$AB=\frac{8}{sin(15^o)}=30.9\ units$

Part 2

Find the length side AC

we know that

$tan(A)=\frac{BC}{AC}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the given values

$tan(15^o)=\frac{8}{AC}$

solve for AC

$AC=\frac{8}{tan(15^o)}=29.9\ units$

X^2 + 1/4 or 7 or 7/2 x + 49

wolverine [178]

Answer:

14

Step-by-step explanation:

Squaring a number (a+b) for example is a^2+2ab+b^2. So you square root x^2 and 49, you get x and seven respectively. you multiply them together and on top of that multiply the product by 2. so 7x*2 is 14x and ye

Alright Soldier I need help, Solve for Percent Error, Calculate the percent error if the experimental value of the density of go

Dima020 [189]

Answer:

Step-by-step explanation:

so the steps to doing this are as follows :

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%

Jazmine can run 4 5/6 miles in 2/3 of an hour. How many miles can she run in 1 hour?

Alona [7]

Answer: she can run $6\dfrac54$ mile sin 1 hour.

Step-by-step explanation:

Given : Distance run by Jasmine in $\dfrac23$ of an hour = $4\dfrac56\text{ miles}=\dfrac{24+5}{6}\text{ miles}$

$=\dfrac{29}{6}$ miles

Distance run by Jasmine in 1 hour = $\dfrac{29}{6}\times\dfrac{3}{2}=\dfrac{29}{4}$ miles.

$=6\dfrac{5}{4}$ miles.

Hence, she can run $6\dfrac54$ mile sin 1 hour.
