Answer:

Step-by-step explanation:
The whole triangle and small triangle are similar (AA). Therefore the sides are in proportion:

<em>cross multiply</em>
<em>use distributive property</em>

<em>subtract 220 from both sides</em>
<em>divide both sides by 55</em>

Answer:
1/ 10 ; 1/15
Step-by-step explanation:
Given that:
Fraction with brown hair = 2 /5
1/4 of brown haired girls have long hairs
2/3 of long, brown haired girls have green eyes.
Fraction of girls with long, brown hair :
1/4 of 2/5
1/4 * 2/5 = (1*2) / (4*5) = 2/ 20 = 1/10
Fraction with long, brown hair and green eyes :
2/3 of Fraction with long, brown hair :
2/3 of 1/10
2/3 * 1/10 = (2*1) / (3*10) = 2/30 = 1/15
Answer:
multiply the length value by 1760
2.4*1760 is 4224
Step-by-step explanation:
The abscissa of the ordered pair, that is the x-coordinate, is equal to 1 and the ordinate, the y-coordinate, is equal to -1. In the cartesian plane, this point lies in the fourth (IV) quadrant. The standard position of the angle is that which has one of its side is in the x-axis.
Solve for the hypotenuse of the right triangle formed.
h = sqrt((-1)² + (1)²) = √2
Below items show the calculation for each of the trigonometric functions.
sin θ = opposite/hypotenuse = y/h = (-1)/(√2) = -√2/2
cos θ = adjacent/hypotenuse = x/h = (1)/√2 = √2/2
tan θ = opposite/adjacent = y/x = -1/1 = -1
