Aleksandr-060686 [28]

Answer:

one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)

other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)

Step-by-step explanation:

ratio of the angles 6:5

when you draw diagonal inside a rhombus it creates four right angled triangle

one angle=90

6x+5x=90 ( the other angles is complimentary)

11x=90

x=90/11

one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)

other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)

in triangle ABC, if the length of side b is 3 centimeters and the measures of angle B and angel C are 45⁰ and 60⁰, respectively,
statuscvo [17]
<h3>Answer: 3.67 centimeters approximately</h3>

Use the law of sines to get this answer

b/sin(B) = c/sin(C)

c/sin(C) = b/sin(B)

c/sin(60) = 3/sin(45)

c = sin(60)*( 3/sin(45) )

c = 3.6742346 approximately

c = 3.67 rounding to nearest hundredth

Make sure your calculator is in degree mode.

Write your own two equations that would have a solution of (3, 6).
andrey2020 [161]

Answer:

y = 2x

y = 3x - 3

Step-by-step explanation:

Hi,

<u>y = 2x</u>

<u>6 = 2(3)</u>

<u>6 = 6</u>

<u>That's a solution</u>

<u>y = 3x - 3</u>

<u>6 = 3(3) - 3</u>

<u>6 = 9 - 3</u>

<u>6 = 6</u>

<u>That's a solution</u>

Hope this helps :)
