What is the value of x? • 7 • 7√2 • 14 • 14√2

Mathematics
1 answer:
MakcuM [25]3 years ago
7 0

Answer:

<h2>7</h2>

Step-by-step explanation:

Look at the picture.

We have the triangle 45° - 45° - 90°. The sides are in ratio 1 : 1 : √2.

Therefore we have the equation:

x\sqrt2=7\sqrt2\qquad\text{divide both sides by}\ \sqrt2\\\\x=7

A certain kite has exactly one acute angle, and it measures 16 degrees. What is the maximum whole-number measure of the angle op
kvv77 [185]

Answer:

In order to do so, we need to use basic algebra. The angles in a kite add up to 360 degrees. so we form the following equation.

x + y + y + 16 = 360

x + y + y = 344 <----(360 -16)

Each letter or variable represents an angle measure. the measures of the three angles left. The 16 degrees is on the bottom of the kite and the angle opposite is the top angle. the two side angles will be the same measure that's why they are both y.

x + 2y = 344

The two side angles will be 90 or greater because there is only 1 acute angle. 90 is the smallest number that can be chosen. so we do the following.

Step-by-step explanation:

x + 2(90) = 344

x + 180 = 344

x = 344-180

x = 164

THE MAXIMUM WHOLE NUMBER MEASURE OF THE ANGLE OPPOSITE OF THE 16 DEGREE ACUTE ANGLE IS 164 DEGREES*
