X^2+8x+15 is the area
because x+5 = length
and x +3 = width
(x+5)(x+3) =
x^2+3x+5x+15 =
x^2+8x+15 (area)
Answer:
-9
Step-by-step explanation:
b² - c²
= 4² - (-5)²
= 16 - 25
= -9
Answer:
Step-by-step explanation:
72% of the students in math 6 = 324
let x represent the students in math 6
turn ur percent to a decimal
0.72x = 324
x = 324 / 0.72
x = 450 students <===
With the help of trigonometric function, the above problems have been calculated. See explanation below.
<h3>What are Trigonometric functions?</h3>
The term "trigonometric function" refers to functions that are periodic in nature and that shed light on how a right-angled triangle's angles and sides relate to one another.
The solutions to x in the respective problems is given as follows:
1) x = 5 /Sin(30°)
x = 10
!) Sin(45°) = 4/x
x = 4/sin(45°)
x = 4√2
I) Cos(45°) = √3 / x
x = √3 / Cos(45°)
x = √6
E) Tan(60°)
= (3√3) / x
x = (3√3) / 3
W) In trigonometry, every right-triangle that is isosceles in nature, the angle made by the legs and the hypotenuse will always equal 45°.
x = 45°
N) x² + x² = (7√2)²
x = 7
V) Tan(60°) = 7 / x
x = 7√3/3
K) x² + x² = (9)²
x = 9/√2
Y) Sin(60°) = 7√3/x
x = 14
M) Sin(30°) = x/11
x = 11/2
T) Sin(45°) = x/√10
x = √5
A) x + 2x + 90° = 180°
x = 30°
O) Sin(45°) = √2 / x
x = 2
R) Tan(30°) = x / 4
x = 4/√3
= 4√3 / 3
S) Sin(60°) = x / (10/3)
x = (5√3) / 3
