Solve for L: d= (LR_2)/(R_2+R_1

D= (LR_2)/(R_2+R_1)
d(R_2+R_1)= LR_2 
d(R_2+R_1)/(R_2)= L 
L= d(R_2+R_1)/(R_2) 

The answer I obtained is the same answer as the third choice. 

L= d(R_2+R_1)/(R_2) 
L= (R_2+R_1)d/(R_2) 
L= (R_2+R_1)(d)/(R_2) 
L= ((R_2+R_1)(d))/(R_2)

What is the value of y?

Amiraneli [1.4K]

Answer:

$\boxed{D. \: 40\degree}$

Step-by-step explanation:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°

So,

$= > 2y \degree + (y + 10)\degree + 50\degree = 180\degree \\ \\ = > 2y\degree + y\degree + 10\degree + 50\degree = 180\degree \\ \\ = > 3y\degree + 60\degree = 180\degree \\ \\ = > 3y\degree = 180\degree - 60\degree \\ \\ = > 3y\degree = 120\degree \\ \\ = > y = \frac{120\degree}{3\degree} \\ \\ = > y = 40\degree$

Answer:

Step-by-step explanation:

Surface area of the object = 2 (lw + wh + hl) = 2 (10× 6 + 6 × 10 + 10 × 10)

= 2 ( 60 + 60 + 100) = 2 × 220 = 440 ft.²
