What are the missing sides in the triangle written as integers or as decimals rounded to the
Alecsey [184]

The value of x is 12.7 and the value of y is 9. The correct option is the third option x = 12.7; y = 9

<h3>Trigonometry </h3>

From the question, we are to determine the values of the missing sides

From the diagram,

Opposite = 9

Adjacent = y

Hypotenuse = x

Included angle = 45°

Using SOH CAH TOA, we can write that

tan 45^\circ= \frac{9}{y}

1 = \frac{9}{y}

∴ y = 9

Since the triangle is a right triangle, we can write that

x² = y² + 9² (<em>Pythagorean theorem</em>)

x² = 9² + 9²

x² = 81 + 81

x² = 162

x = √162

x = 12.7

Hence, the value of x is 12.7 and the value of y is 9. The correct option is the third option x = 12.7; y = 9

At which one of the following times is the angle between the hands of a clock exactly one straight angle? a)12:00 b)12:30 b)3:45
Marta_Voda [28]
12:00 will have both hands pointing up
12:30 will have the straight line at the half past part but it will not be exactly on the 12
3:45 it will be past the 3 and exactly on 45 so it will not work
And 6:00 will be a straight line as one hand will be at the 12 and and it will be straight on the 6 as it is on the hour so the answer is d
