Can someone do 15?!?!?
andrew-mc [135]

<u>Given</u>:

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.

<u>Value of x:</u>

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

Thus, we have;

sin \ \theta=\frac{opp}{hyp}

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

Thus, we have;

sin \ x=\frac{23}{31}

Dividing, we get;

sin \ x=0.74

Taking sin ^{-1} on both sides of the equation, we get;

x=sin^{-1}(0.74)

x=47.7

Rounding off to the nearest whole integer, we get;

x=48

Thus, the value of x is 48°

Hence, Option c is the correct answer.

Find x,y, and z and please show all work.
lana [24]

Answer:

x = 47°

y = 10

z = 5

Step-by-step explanation:

They share the middle line which is one side. It's given that side y is congruent to the side with a value of 5. Angle X and the non labeled angel are also congruent to each other. Using SAS (side angle side) we can conclude the 2 triangles are congruent, which means all angles and sides are congruent and equal.

The angles of a triangle add to 180.

x+90+43=180

x=47

z is congruent/equal to 5 since they are congruent and equal triangles. Therefore z=5

Y is congruent to side 10, which also means it is equal to 10. Therefore y=10
