For the given triangle, x = 5.1 cm and y = 6.1 cm.

Step-by-step explanation:

Step 1:

In the given triangle, the angle is 50°. It is given that the opposite side has a length of y cm and the adjacent side has a length of y cm. The hypotenuse of the triangle measures 8 cm.

To determine the length of the opposite side of the triangle, we use the sin of the given angle.

To determine the length of the adjacent side of the triangle, we use the cos of the given angle.

$sin \theta = \frac{oppositeside}{hypotenuse} , cos \theta = \frac{adjacentside}{hypotenuse}.$

Step 2:

In the given triangle,

The length of the opposite side = y cm,

The length of the adjacent side = x cm,

The length of the hypotenuse = 8 cm,

The angle of the triangle = 50°.

$sin \theta = \frac{oppositeside}{hypotenuse} , sin 50 = \frac{y}{8}.$

$y = 0.7660 (8) = 6.128.$

$cos \theta = \frac{adjacentside}{hypotenuse} , cos 50 = \frac{x}{8}.$

$x = 0.6427 (8) = 5.1416.$

So x = 5.1416 cm and y = 6.128 cm. Rounding these off to one decimal place, we get x = 5.1 cm and y = 6.1 cm.

Please help me ASAP I’m really confused.

Some key definitions:

Reflexive property: angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.

Symmetric property: you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.

Transitive property: If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.

So for the first clue, you have the reflexive property.

The second clue is the symmetric property.

The third clue is the transitive property.
