Right △ABC has its right angle at C, BC=4 , and AC=8 .
PolarNik [594]

Answer:

Part A) sin(A)=\frac{\sqrt{5}}{5}

Part B) tan(B)=2

Part C) sec(A)=\frac{\sqrt{5}}{2}

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the length side AB (hypotenuse of the right triangle)

Applying the Pythagorean Theorem

AB^2=BC^2+AC^2

substitute the given values

AB^2=4^2+8^2

AB^2=80

AB=\sqrt{80}\ units

simplify

AB=4\sqrt{5}\ units

step 2

Find sin(A)

we know that

In the right triangle ABC

sin(A)=\frac{BC}{AB} ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

sin(A)=\frac{4}{4\sqrt{5}}=\frac{\sqrt{5}}{5}

step 3

Find tan(B)

we know that

tan(B)=\frac{AC}{BC} ----> by TOA (opposite side divided by adjacent side)

substitute the values

tan(B)=\frac{8}{4}=2

step 4

Find sec(A)

we know that

sec(A)=\frac{1}{cos(A)}

cos(A)=\frac{AC}{AB} ----> by CAH

so

sec(A)=\frac{AB}{AC}

substitute the values

sec(A)=\frac{4\sqrt{5}}{8}

simplify

sec(A)=\frac{\sqrt{5}}{2}

Multiply and find product in its lowest terms.
soldi70 [24.7K]

Answer:

1/30

Step-by-step explanation:

\frac{4}{9} \times \frac{3}{5} \times \frac{1}{8} \\ \\ =\frac{4 \times 3 \times 1}{9 \times 5 \times 8} \\ \\ =\frac{1}{3 \times 5 \times 2} \\ \\ =\frac{1}{30}

PLEASE HELP BRAINLY - which option is correct?
LuckyWell [14K]

Answer:

y > \frac{2x}{3} + 1

Step-by-step explanation:

Given:

The graph in the attachment where the coordinates are (3,3) and (-3,-1)

Required:

Which inequality represent the graph

The first step is to determine the slope of the graph

m = \frac{y_2 - y_1}{x_2 - x_1}

Where m represents the slope, (x_1, y_1) = (3,3) and (x_2, y_2) = (-3,-1)

m = \frac{-1 - 3}{-3 - 3}

m = \frac{-4}{-6}

Simplify to lowest term

m = \frac{2}{3}

Next is to determine the equation of the line using the slope formula

m = \frac{y - y_1}{x - x_1}, (x_1, y_1) = (3,3)  and m = \frac{2}{3}

\frac{2}{3} = \frac{y - 3}{x - 3}

Cross multiply

2 * (x - 3) = 3 * (y - 3)

Open both brackets

2 x - 6 = 3y -9

Collect like terms

2 x - 6 +9= 3y

2 x+3= 3y

Divide through by 3

\frac{2x}{3} + \frac{3}{3} = \frac{3y}{3}

\frac{2x}{3} + 1 = y

Reorder

y = \frac{2x}{3} + 1

Next is to determine the inequality sign

  • The dotted lines on the graph shows that the inequality sign is either > or <
  • Since the shaded region is the upper part of the graph, then the > inequality sign will be considered,

The inequality becomes

y > \frac{2x}{3} + 1
