Answer:

  m∠Y = 40°

Step-by-step explanation:

The sum of complementary angles is 90°. If we let s and y represent m∠S and m∠Y, respectively, the angle measures in degrees satisfy ...

  s + y = 90

  (4y -110) +y = 90 . . . . . . . . substitute for s

  5y = 200 . . . . . . . . . add 110

  y = 40 . . . . . . . divide by 5

The measure of angle Y is 40°.

Can someone help me plz
wolverine [178]

Answer:

75°

Step-by-step explanation:

Recall: SOH CAH TOA

Reference angle = ? = θ

Side length opposite to reference angle = 27

Hypotenuse length = 28

Apply SOH, which is:

sin(\theta) = \frac{Opposite}{Hypotenuse}

Substitute

sin(\theta) = \frac{27}{28}

\theta = sin^{-1}(\frac{27}{28})

\theta = 75 degrees (nearest degree)

The right triangle above has height h centimeters and hypotenuse t centimeters. What is the area, in square centimeters, of the
White raven [17]

Answer:

A = \frac{h\sqrt{t^{2} - h^{2}}}{2}

Step-by-step explanation:

Right triangle:

height h, width w, hypotenuse h

Area is: A = \frac{h*w}{2}

Pytagoras theorem: h^{2} + w^{2} = t^{2}

In this question:

To find the area, in terms of h and t, we have to write w as a function of h and t. So

h^{2} + w^{2} = t^{2}

w^{2} = t^{2} - h^{2}

w = \sqrt{t^{2} - h^{2}}

So the area is:

A = \frac{h*w}{2}

A = \frac{h\sqrt{t^{2} - h^{2}}}{2}
