Answer: 77 degrees

Step-by-step explanation:

By the law of sines,

\frac{\sin 13^{\circ}}{6}=\frac{\sin A}{26}\\\sin A=\frac{26 \sin 13^{\circ}}{6}\\A=\sin^{-1} \left(\frac{26 \sin 13^{\circ}}{6} \right) \approx 77^{\circ}

How do you use equivalent fractions to compare the fractions in each pair
Alenkasestr [34]
Firstly you need to to reduce to a common denominator by multiplYing the whole fraction. This way you have to multiply 4/5 by 2 (both numerator and denominator). so 4/5 = 8/10. And now you have 8/10 and 9/10. You compare only numerators. This way you have 8/10 <9/10. Same goes for 2/3 and 5/8. Only here you need to multiply both fractions. The common denominator here is 24. So you have to multiply 2/3 by 8 and 5/8 by 3. You now have to compare 16/24 and 15/24. 16/24>15/24.

Please help. Don’t understand this math problem!!!
Fittoniya [83]

Answer:

1). Option (C)

2). Option (A). degree of 3 = 0

Step-by-step explanation:

A polynomial having one term is called 'Monomial' in algebraic terms.

3 is a number that is a polynomial with a single term.

Therefore, the given expression is a polynomial.

Hence Option (C) is the answer.

3 can be written as 3x⁰ (Since x⁰ = 1)

Therefore, degree of the polynomial is 0.

Option (A). degree of the polynomial = 0

Can someone help me out with this please? I suck at fractions
xxMikexx [17]

164 inches x \frac{1 foot}{12 inches} = \frac{41}{3}ft

147 inches x \frac{1 foot}{12 inches} = \frac{49}{4}ft

2\frac{1}{4}ft = \frac{9}{4}

Perimeter = 2L + 2w - 1doorway

                 = 2(\frac{41}{3}) + 2((\frac{49}{4}) - \frac{9}{4}

                = \frac{82}{3} + \frac{98}{4} - \frac{9}{4}

                = \frac{82}{3} + \frac{89}{4}

                 = (\frac{4}{4} )\frac{82}{3} + (\frac{3}{3} )\frac{89}{4}

                 = \frac{328}{12} + \frac{267}{12}

                 = \frac{595}{12}

                = 49\frac{7}{12}ft

******************************************************************************

b) 49\frac{7}{12}ft ÷ 8ft = 6.2

7 boards need to be purchased
