Answer:
It's (D)
Step-by-step explanation:
<span>2 * 10^-4 - 1 * 10^-5
= 10^-4 ( 2 - 1 * 10^-1)
= 10^-4 ( 2 - 0.1)
= 10^-4 (1.9)
= 1.9 * 10^-4

The complete question in the attached figure
we know that
When we know <span>two sides and the included angle the formula for calculate the area is
</span>Area=(1/2)*a*b*sin C
in this problem
let
a=20
b=12
C=68°
Area=(1/2)*20*12*sin 68°------> Area=111.26 units²-----> Area=111.3 units²
the answer is111.3 units²
Answer:
The uses of flowcharts are numerous in industries, such as entertainment, engineering, physical sciences, and computer programming. The purpose of flowcharts are to communicate how a process works or should work without any confusing technical jargon, if i have answered your question incorrectly i truly apologize but there isn't much to your question.
Answer:
The answer to your question is 19 in²
Step-by-step explanation:
Data
angle = Ф = 25°
hypotenuse = 10 in
Area = ?
Process
1.- Calculate the long and short legs of this triangle using trigonometric functions.
sin Ф = Opposite side / hypotenuse
-Solve for Opposite side
Opposite side = hypotenuse x sin Ф
-Substitution
Opposite side = 10 x sin 25
-Result
Opposite side = 4.22 in = short leg (height)
cos Ф = Adjacent side / hypotenuse
-Solve for Adjacent side
Adjacent side = hypotenuse x cosФ
-Substitution
Adjacent side = 10 x cos 25
-Result
Adjacent side = 9.06 in = long leg = base
2.- Calculate the area
Area = base x height / 2
-Substitution
Area = 9.06 x 4.22 / 2
-Result
Area = 19.12 in² ≈ 19 in²
