Step-by-step explanation:
5^6
242.9 . I worked it out on a piece of paper so it might be right .
<span> 10 x 10^9 = 10^10
</span><span>99 x 10^6 = 100 x 10^6 = 10^8
10^10 - 10^8 = 10^2 = 100
answer: </span><span>C) 100 times larger </span>
<span>✦ Find the cosine function.
</span><span>✦ CosX = 4.2 / 5 - 0.85
</span><span>✦ Find the inverse cosine function.
</span><span>✦ Accros0.84 = X*
</span><span>✦ = 32.86
</span>
The answer is 32.86 degrees.
