Answer:

20 cm

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

15^2 +b^2 = 25^2

225+b^2 = 625

Subtract 225 from each side

225+b^2 -225 = 625-225

b^2 = 400

Take the square root of each side

sqrt(b^2) = sqrt(400)

b = 20

Two angles of a quadrilateral are of measures 75° and 117° respectively and the other two angles are equal find the measure of e

insens350 [35]

<u>Answer:</u>

<u>Step-by-step explanation:</u>

The sum of interior angles of a quadrilateral is 360°.

If we consider the measure of one of the unknown angles to be $x$ °, we can set up the following equation:

$x + x + 75^\circ + 117^\circ = 360^\circ$

Now we can solve for $x$ :

⇒ $2x + 192^\circ = 360^\circ$

⇒ $2x = 360^\circ - 192^\circ$ [subtracting 192° from both sides]

⇒ $2x = 168^\circ$

⇒ $x = \frac{168^\circ}{2}$ [dividing both sides by 2]

⇒ $x = \bf84^\circ$

Therefore, the other two angles each have a measure of 84°.
