Answer:

sqrt(2)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 45 = x/2

2 sin 45 =x

2 (sqrt(2)/2) =x

sqrt(2) =x

Answer:

x^9

Step-by-step explanation:

The rule of exponents that applies is ...

(a^b)^c = a^(b·c)

For your problem, you have a=x, b=(3/2), c=6, so ...

(x^(3/2))^6 = x^(3/2·6) = x^9

What is 3+0.5(4a+8)=9-2a is your solving for (a).

Nady [450]

Answer:

$a = 1/2$

Step-by-step explanation:

Step 1: Distribute

$3 + 0.5(4a + 8) = 9 - 2a$

$3 + (0.5 * 4a) + (0.5 * 8) = 9 - 2a$

$3 + 2a + 4 = 9 - 2a$

Step 2: Combine like terms

$(3 + 4) + 2a = 9 - 2a$

$7 + 2a = 9 - 2a$

Step 3: Subtract 7 from both sides

$7 + 2a - 7 = 9 - 2a - 7$

$2a = 2 - 2a$

Step 4: Add 2a to both sides

$2a + 2a = 2 - 2a + 2a$

$4a = 2$

Step 5: Divide both sides by 4

$4a / 4 = 2 / 4$

$a = 1/2$

Answer: $a = 1/2$
