which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle?

sdas [7]

Answer:

Obtuse triangle.

Step-by-step explanation:

Side a = 5

Side b = 2

Side c = 4

Angle ∠A = 108.21° = 108°12'36" = 1.88862 rad

Angle ∠B = 22.332° = 22°19'54" = 0.38976 rad

Angle ∠C = 49.458° = 49°27'30" = 0.86321 rad

Since one angle is above 90 degrees, the triangle is obtuse triangle.

This cannot be an acute triangle.

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°.

What is the length of bc? AC = 8 AB = 17

padilas [110]

Using Pythagoras theorem,

$17^2=8^2+(BC)^2\implies BC=\sqrt{17^2-8^2}=15$ .

Hope this helps.
