Can someone do 15?!?!?

Given:

The given triangle is a right triangle.

The length of the hypotenuse is 31 units.

The length of the leg is 23 units.

One of the angle is x.

We need to determine the value of x.

Value of x:

The value of x can be determined using the trigonometric ratio.

Thus, we have;

Substituting , the side opposite to the angle x measures 23 units and the hypotenuse is 31.

Thus, we have;

Dividing, we get;

Taking on both sides of the equation, we get;

Rounding off to the nearest whole integer, we get;

Thus, the value of x is 48°

Hence, Option c is the correct answer.

17.2

Step-by-step explanation:

(14)2+(10)2=

 c2\,\,c^{2}c2

Use the Pythagorean Theorem.

196+100=196+100=196+100=

 c2\,\,c^{2}c2

Simplify.

296=296=296=

 c2\,\,c^{2}c2

Simplify.

±296=\pm\sqrt{296}=±296

​=

 c2\,\,\sqrt{c^{2}}c2

​

Square root both sides.

17.204650...=17.204650...=17.204650...=

 c\,\,cc

Simplify. Ignore negative root, as length must be positive.

17.2≈17.2\approx17.2≈

 c\,\,cc

Round to the nearest tenth.
