Solve The right triangle

Step-by-step explanation:

It is convenient to use the Pythagorean theorem to find the hypotenuse, given the side lengths.

  WY² = WX² +XY²

  WY² = 2² +1² = 4 +1 = 5 . . . . . fill in the given numbers

  WY = √5

  WY ≈ 2.2

It is convenient to use the tangent relation to find the angles.

  tan(W) = XY/XW = 2/1 = 2

  W = arctan(2) ≈ 63.4°

You can do likewise for angle Y, or you can simply find the complement of angle W. (The acute angles in a right triangle are complements of each other.)

  Y = 90° -W = 26.6°

The angle measures are ...

b

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
