In abc above,what is the length of ad

Nezavi [6.7K]

Answer:

Step-by-step explanation:

First calculate BD using sine ratio in Δ BCD and the exact value

sin60° = $\frac{\sqrt{3} }{2}$ , thus

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{BD}{BC}$ = $\frac{BD}{12}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2BD = 12 $\sqrt{3}$ ( divide both sides by 2 )

BD = 6 $\sqrt{3}$

-----------------------------------------------------------

Calculate AD using the tangent ratio in Δ ABD and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , thus

tan30° = $\frac{opposite}{adjacent}$ = $\frac{AD}{BD}$ = $\frac{AD}{6\sqrt{3} }$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

$\sqrt{3}$ AD = 6 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

AD = 6 → B

James has a rectangular plot of land that is 250 feet long and x feet wide. He wants to build a fence around the plot of the lan

Margarita [4]

Answer:

= 221

Step-by-step explanation:

Lenght = 250

Width= x

Perimeter = 2 (l+b) = 942

2 x (250 +x) = 942

500 + 2x = 942

2x = 942 - 500= 442

x = 442 /2 = 221

I hope Im right!!

(6+3)-+8-7)= (1+4)+(10-8)= (3-3+(9+1)= (10-2)+(10-8)= 2+(0+1+2+3)= (10-1-2-3)+4=

JulijaS [17]

Answer:

6+3-8-7 = 8

1+4+10-8 = 7

3-3+9+1 = 10

10-2+10-8 = 10

2+0+1+2+3 = 8

10-1-2-3+4 = 8

Step-by-step explanation:

i don't know if these are supposed to be easy or not lol but thanks for the points :p
