Answer:
a = 11.71 ; b = 15.56
Step-by-step explanation:
For this problem, we need two things. The law of sines, and the sum of the interior angles of a triangle.
The law of sines is simply:
sin(A)/a = sin(B)/b = sin(C)/c
And the sum of interior angles of a triangle is 180.
45 + 110 + <C = 180
<C = 25
We can find the sides by simply applying the law of sines.
length b
7/sin(25) = b/sin(110)
b = 7sin(110)/sin(25)
b = 15.56
length a
7/sin(25) = a/sin(45)
a = 7sin(45)/sin(25)
a = 11.71

Answer:
<em>A = 48.81°</em>
Step-by-step explanation:
<u>Angles in a Right Triangle</u>
When the side lengths of a right triangle are known and an angle must be determined, we can use the trigonometric ratios that relate angles and sides.
The tangent ratio is defined as:
Opposite leg to angle A is 8 and adjacent leg is 7, thus:
Using the inverse tangent funcion:
Calculating:
A = 48.81°
Answer:
Width: 7 Length: 10
Step-by-step explanation:
Width: x
length: 2x-4
Area: 70 meters squared
(2x-4)x=70
2x^2-4x=70
2x^2-4x-70=0
2(x^2-2x-35)=0
(x-7)(x+5)=0
x cannot be negative so x=7
