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

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:

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

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