Answer:

x=10

Step-by-step explanation:

So, we got our equation:

$\frac{x+4}{2}=y$

We'll multiply both sides by 2 to get rid of that fraction.

x+4=14

Then, we just subtract 4 from both sides.

x=10

Answer:

A. n = 5

Step-by-step explanation:

S = n² + n

When S = 30:

n² + n = 30

Subtract 30 from both sides: n² + n - 30 = 0

Factorize: (n - 5)(n + 6) = 0

Therefore n = 5 or -6

As n > 2, then n = 5 only

<span>Find missing length :
</span>
a² + b² = c²
c² = 19² + 34²
c² = 1517
c = √1517
c = 38.95 units.

Find missing angle A:

$\dfrac{a}{\sin(a)} = \dfrac{c}{\sin(c)}$

$\dfrac{19}{\sin(a)} = \dfrac{38.95}{\sin(90)}$

$\sin(a) = 0.488$

$a = sin^{-1} (0.488)$

$a = 29.2 \textdegree$

Find Missing B:

$\dfrac{b}{\sin(b)} = \dfrac{c}{\sin(c)}$

$\dfrac{34}{\sin(b)} = \dfrac{38.95}{\sin(90)}$

$\sin(b) = 0.873$

$b = sin^{-1}(0.873)$

$b = 60.8 \textdegree$

Answer: Missing length = 38.95 units ; Missing angles = 29.2° and 60.8°
