4 0

Answer

Step-by-step explanation:

Let x be Chris's age before, x+35 be Chris's age now.

2(x+35) = 35+7x

2x+70 = 35 +7x

35=5x

7=x

7+35=42

<u>Answer</u>:

x = 20

<u>Explanation</u>:

all the interior angles in the triangle is 180°

<u>therefore</u>:

4x - 17° + 71° + 46° = 180°

4x + 100° = 180°

4x = 180° - 100°

4x = 80°

x = 20°

Which is equivalent to sin^-1(.75)

Neko [114]

<h2>Answer: 0.85 radians</h2>

Step-by-step explanation:

We have the following trigonometric expression:

$sin^{-1}(0.75)=arcsin(0.75)$

The result of this calculation is:

$sin^{-1}(0.75)=48.59\°$ where the angle is in degrees

If $360\°=2\pi rad$ then:

$48.59\°(\frac{2\pi rad}{360\°}=0.848 rad \approx 0.85 rad$

Therefore the answer is 0.85 radians
