Given parameters:

Weight of Tan = 146pounds

Unknown:

Weight of Minh = ?

Following this problem step wisely, we can derive a solvable algebraic equation;

Let the weight of Minh = M

In the second sentence, we see that Minh weighs 15pounds more than Tan;

So;

M = 15 + Weight of Tan

Since we already know the weight of Tan,

Weight of Minh = 15 + 146 = 161pounds

We clearly see that Minh's weight will be 161 pounds.

Answer:

Step-by-step explanation:

let ∠GEF=x

then ∠GFE=90-x

$\frac{GH}{EH}=tan x\\GH=EH~ tan x\\or~ GH=a ~tan x=6 tan x\\\frac{GH}{FH}=tan (90-x)=cot x\\GH=FH*cot x\\GH=b*cot x=27 cot x\\6 tan x=27 cotx\\\frac{tan x}{cot x}=\frac{27}{6}\\tan ^2 x=\frac{27}{6}=\frac{9}{2}\\sec^2x-tan^2x=1\\sec^2 x=1+tan ^2x=1+\frac{9}{2}=\frac{11}{2}\\\frac{EG}{EH}=sec x\\ EG=EH sec x=a sec x= 6 sec x=6\sqrt{\frac{11}{2} } =3\sqrt{22} \approx 14.07$

Answer:

$82.50

Step-by-step explanation:

8.75 * 8 = 70

5 * 2.50 = 12.5

70 + 12.5 = 82.5

So, one employee would earn a total of $82.50 which also means that each employee earned $82.50

Round to the nearest tenth.

Answer: Angle A = 53.9 degrees

Step-by-step explanation: We have a right angled triangle with two sides clearly given and one angle to be calculated. If the angle to be calculated is angle A, then having angle A as our reference angle, line AC (10 units) is the adjacent, line CB is the opposite while line AB (17 units) is the hypotenuse. Having been given the adjacent and the hypotenuse, we can now use the trigonometric ratio as follows;

CosA = adjacent/hypotenuse

CosA = 10/17

CosA = 0.5882

By use of the calculator or table of values,

A = 53.97

Approximately to the nearest tenth,

A = 53.9 degrees
