what are the lengths of the legs of a right triangle in which one acute angle measures 19° and the hypotensue is 15 units long?
givi [52]
Refer to the diagram shown below.

Given:
m∠A = 19°
c = 15

By definition,
sin A = a/c
Therefore
a = c*sin A = 15*sin(19°) = 4.8835

cos A = b/c
Therefore
b = c*cos A = 15*cos(19°) =14.1828

Answer:
The lengths are 4.88, 14.18, and 15.00  (nearest hundredth)

What’s.the perimeter of a square with an area of 49 cm2
Free_Kalibri [48]

Answer:

<h3>28</h3>

Step-by-step explanation:

Area of a square =

s^2

Perimeter =

4\times s

Where s = side

Solve for s using the area

A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7

Find the perimeter

4\times s\\\\= 4 \times 7\\\\= 28
