Solve angle X to 1 dp
geniusboy [140]

Answer:

x ≈ 57.8°

Step-by-step explanation:

using the Sine rule in the triangle

\frac{11}{sinx} = \frac{8}{sin38} ( cross- multiply )

8 × sinx = 11 × sin38° ( divide both sides by 8 )

sinx = \frac{11sin38}{8} , then

x = sin^{-1} ( \frac{11sin38}{8} ) ≈ 57.8° ( to 1 dec. place )

Evaluate expression -16 squared and write the result in form a + bi
coldgirl [10]

Writing it in the form of a+bi we get 0+4i

Step-by-step explanation:

We need to evaluate expression -16 squared and write the result in form a+bi

The given expression is: \sqrt{-16}

We know that \sqrt{-1}=i

We know that 16= 4x4 = 4^2

Putting values:

\sqrt{-16}=\sqrt{-1}\sqrt{16}\\=\sqrt{4^2}i\\=4i

So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i
