Answer:
12/13
Step-by-step explanation:
we know this is a right triangle, and we know that the hypotenuse is the longest side. so we can already say that the hypotenuse of the triangle is DF or 78.
when you draw it out, you find that the shortest leg is 30 and the second is 72 and the hypotenuse is 78. we also know that cosine is adjacent/hypotenuse. once you draw the triangle and notice which side is adjacent to angle F, just fit it into the formula and you get:
cos F = 72/78
cos F = 12/13
Answer:
x^2 = 121
Step-by-step explanation:
Sea el ancho del terreno x metros
Dado que la longitud es el doble del ancho, entonces la longitud será 2 * x = 2x
Matemáticamente, el área de un rectángulo es;
Anchura longitud Por lo tanto, tenemos
x * 2x = 242 metros cuadrados
Así; 2x ^ 2 = 242
x ^ 2 = 242/2
x ^ 2 = 121
Answer:
<h2>y - 5 = x - 20</h2>
Step-by-step explanation:
The equation of a linear function in
slope-intercept form: 
point-slope form: 
standard form: 
general form: 
1.
y(x - 1) = 9
xy - y = 9 NO
2.
y - 5 = x(-x + 2)
y - 5 = -x² + 2x NO
3.
y(y - 1) = x + 25
y² - y = x + 25 NO
4.
y - 5 = x - 20
y - 5 = 1(x - 20) YES <em>(it's a point-slope form)</em>
THE ANSWER IS: I=3s+4
because 4 years older would simply be addition while the question asks for the reader to multiply 3 times the brothers AGE which is represented by S
