Mathematics
2 answers:
Serggg [28]3 years ago
6 0

Answer:

<h2>a = 9.2</h2><h2>b = 8.65</h2><h2 />

Step-by-step explanation:

<u>First</u><u> </u><u>Question</u>

To find a we use sine

sin ∅ = opposite / hypotenuse

a is the opposite

12.8 is the hypotenuse

sin 46 = a / 12.8

a = 12.8 sin 46

<h3>a = 9.2</h3>

<u>Sec</u><u>ond</u><u> question</u>

To find b we use cosine

cos∅ = adjacent / hypotenuse

b is the adjacent

16.8 is the hypotenuse

cos 59 = b / 16.8

b = 16.8 cos 59

<h3>b = 8.65</h3>

Hope this helps you

Step-by-step explanation:

  • a

sin 46°= a/12.8

a = sin46° * 12.8 = 9.20

  • b

cos59°=b/16.8

b = cos59°*16.8 = 8.65

17−5r+9r=12+6r−1<br> what is r?
jonny [76]

Answer:

r=3

Step-by-step explanation:

simplify each side

4r+17=6r+11

Subtract 4r from both sides.

17=2r+11

Subtract 11 from both sides

6=2r

divide both sides by 2

3=r
