Answer:

d=2√2, b= $\frac{3\sqrt{2}}{2}$

Step-by-step explanation:

first triangle is a 30-60-90

so, sides x-x√2-2x

x=2

therefore d=2√2

second triangle is 45-45-60

sides, 1-1-√2

which means b√2=6

b=6/√2 ---> multiply by √2/√2 to get ride of the √2 denominator

b=6√2/4 , simplify

b= $\frac{3\sqrt{2}}{2}$

The diagonal of a square has length 10√2. Find the area of the square.

alex41 [277]

Answer: $A = 100$ square unit

Step-by-step explanation:

The formula for calculating the area of a square when the diagonal is given is :

$Area = d^{2} / 2$

That is :

$A = \frac{(10\sqrt{2})^{2}}{2}$

$A = \frac{100(2)}{2}$

$A = 100$ square unit

b r = 178 + h;

b r + h = 676;

then, 178 + 2h = 676 => h = 498/2 = 249 => b r = 178 + 249 = 427

Answer:

676

Step-by-step explanation:

h=b+178=427

b=b=249

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

(b+178)+b=676

2b+178=676

2b=498

b=249

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

249+427=676
