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:
(0,-1)
Step-by-step explanation:
Answer:
P = 20x + 6
Step-by-step explanation:
Perimeter formula:
P = 2(l + w)
Given:
l = 8x - 1
w = 2x + 4
Work:
P = 2(l + w)
P = 2(8x - 1 + 2x + 4)
P = 2(10x + 3)
P = 20x + 6
Answer:
$24,000
Step-by-step explanation:
After putting in trust they have left:
48000 - 9600 = $38,400
If Tori gets 3/8, Akira will get the remaining (1 - 3/8 = 5/8). So Akira will get:
Hence akira will get $24,000
Answer:
x = 109
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
The lower base angle is supplementary to the upper base angle on the same side, thus
x + x - 38 = 180 , that is
2x - 38 = 180 ( add 38 to both sides )
2x = 218 ( divide both sides by 2 )
x = 109
