$\boldsymbol{\boxed{\alpha = 105 ^{\circ}}}$

Explanation:

$\alpha = \dfrac{7}{12} \pi$ in radians

For the formula:

$\boxed{1 \ \text{rad} =\bigg( \frac{180}{\pi} \bigg)^{\circ}}$

$\alpha$ in degrees:

$\alpha = \dfrac{7}{12} \pi \cdot \dfrac{180^{\circ}}{\pi} = 105 ^{\circ}$

We want to solve the sum:

6.74*10⁴ + 8.95*10⁴

first, we take the common factor 10⁴ out, so we get:

(6.74 + 8.95)*10⁴

Now we solve the sum:

(15.66)*10⁴

Now we want to rewrite it in exponential form, wo we can rewrite it as:

(15.66)*10⁴ = (1.566*10)*10⁴ = (1.566)*10*10⁴ = (1.566)*10⁴⁺¹ = 1.566*10⁵

k = 5.
