In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?

Marat540 [252]

Answer:

We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.

Step-by-step explanation:

Pythagorean theorem: a2 + b2 = c2.

Sines: sin A = a/c, sin B = b/c.

Cosines: cos A = b/c, cos B = a/c.

Tangents: tan A = a/b, tan B = b/a.

the length of a rectangle is represented by (6x-2), and the width is represented by (x-1). which expression best represents the

Scrat [10]

Answer:

14x - 6

Step-by-step explanation:

P = 2(length + width)

P = 2(6x - 2 + x - 1) = 2(7x - 3) = 14x - 6

In a paper bag, 7 of the 15 marbles are yellow. In a cloth bag, 2 of the 15 marbles are yellow. If Tim randomly draws one marble

ddd [48]

Answer :

$\frac{7}{15}$ × $\frac{2}{15}$ = $\frac{14}{225}$

Step-by-step explanation:

P( $Event_{1}$ ) = choosing yellow marble from paper bag = $\frac{favourable outcomes}{possible outcomes}$ = $\frac{7}{15}$

P( $Event_{2}$ ) = choosing yellow marble from cloth bag = $\frac{favourable outcomes}{possible outcomes}$ = $\frac{2}{15}$

∵ Resultant outcome is dependent upon both the events and both events are independent from each other, so we can apply intersection rule [ P(A∩B)=P(A)×P(B) ] here

∴ Probability ( Both marbles are yellow) = P( $Event_{1}$ ) × P( $Event_{2}$ ) = $\frac{7}{15}$ × $\frac{2}{15}$

Use the graph of the polynomial function to find the factored form of the

Fofino [41]

Answer:

Step-by-step explanation:

when factoring, the two numbers that you get after you factor are also called solutions, or x intercepts. from this, we know that since the line crosses at positive 1 and positive 9, the answer must be -1 and -9 as you flip the sign after factoring to get the real answer

(ps you can also just plug in all of the answer choices to desmos and see which one matches your graph)

The table shows how the average cost of gasoline at one gas station changed over the past four months. Which graph might a magaz

Dafna11 [192]

Answer:

B/2

Step-by-step explanation:

The table mentions that the time actually starts from the end of the first month, so it cannot be graph one, which starts from 0.

Also, we can see that the values are decreasing over time, meaning it cannot be graph 3, which shows an increase.

thus, we settle the Answer as Graph 2, which satisfies all the needs.

Hope this helps.
