Find the degree triangle

1 answer:

coldgirl [10]2 years ago

6 0

Answer:

A) 7

Step-by-step explanation:

Because the triangles are congruent to each other, then their corresponding angles are also congruent to each other. Thus, angles Z and V are congruent to each other:

$\angle Z=\angle V\\\\40^\circ=(5n+5)^\circ\\\\35=5n\\\\7=n$

Therefore, your answer is A.

A ferry departs from a port along the Sands River at 10:00 am. The ferry travels at a speed of 15 mph in still water and returns

jek_recluse [69]

Answer:

Speed of river's current = 5 mph

Step-by-step explanation:

Let 'd' be the distance covered

Let x be the speed of the rivers current

Speed upstream = 15-x

speed downstream = 15+x

Time = distance / speed

time upstream = $\frac{d}{15-x}$

time downstream = $\frac{d}{15+x}$

the ferry trip upstream takes twice as long as its return trip downstream

$\frac{d}{15-x}$ = $\frac{2d}{15+x}$

divide both sides by d

$\frac{1}{15-x}$ = $\frac{2}{15+x}$

cross multiply

$15+x= 2(15-x)$

$15+x= 30-2x$

Add 2x on both sideds

$15+3x= 30$

subtract 15 from both sides and divide by 3

$3x=15$

x=5

Speed of river's current = 5 mph

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form

Ahat [919]

Answer:

-3x + 4y = 40.

Step-by-step explanation:

Let's convert the equation to standard form:

y - 4 = 3/4(x + 8)

y - 4 = 3/4 x + 6

y = 3/4x + 10

Multiply through be 4:

4y = 3x + 40

-3x + 4y = 40 (answer).
