Find all the missing elements:

Evgesh-ka [11]

Answer:

a=10.8; c=4.3

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees.

Two of the angles are given as 40 deg and 120 deg.

Subtract the measures of both from the sum to get the last angle:

180-40-120=20; ∠C=20°

Using Law of Sines: $\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}$

$\frac{a}{sin120}=\frac{8}{sin40}; a=\frac{8*sin120}{sin40}; a=10.77837084$

$\frac{c}{sin20}=\frac{8}{sin40}; a=\frac{8*sin20}{sin40}; c=4.25671109$

1/4 foot every 3/4 hour how many feet in one hour

RUDIKE [14]

For this case we propose a rule of three:

$\frac {1} {4}$ foot -------------> $\frac {3} {4}$ hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

$x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}$

So, we have $\frac {1} {3}$ foot every hour.

Answer:

$\frac {1} {3}$ foot every hour

Simplify the expression. (16 − 9)^11 divided by [(3 + 4)^2]4

densk [106]

Do 16-9 which equals 7, then (7)^11=77 1.=77

this one add 3+4 which equals 7 then do 7^2= 49 then 4x49=196 2.=196
