What is measure of angle R?

Musya8 [376]

Answer:

$R=28.07^o$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle PQR

The sine of angle R is equal to divide the opposite side to angle R (PQ) by the hypotenuse (PR)

$sin(R)=\frac{PQ}{PR}$

substitute the values

$sin(R)=\frac{8}{17}$

Find the measure of angle R

using a calculator

$R=sin^{-1}(\frac{8}{17})$

$R=28.07^o$

Answer:

h = 39.1918 in
s = 44 in
a = 40 in
e = 48.3322 in
r = 20 in
V = 20902.3 in³
L = 3520 in²
B = 1600 in²
A = 5120 in²

h = height
s = slant height
a = side length
e = lateral edge length
r = a/2 
V = volume
L = lateral surface area
B = base surface area 
A = total surface area

Jens motorboat travels at a speed of 40 miles in Stillwater booth river flows at a speed of 4 mph how long will it take Jen to t

olganol [36]

Recall your d = rt, distance = rate * time.

bearing in mind that, when she's going downstream, she's not going 40 mph, she's going 40 + 4 mph, because the stream is adding its speed to it.

likewise, when she's going upstream, she's going 40 - 4 mph, because the stream is eroding speed from it, thus

$\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
Upstream&10&40-4&u\\
Downstream&10&40+4&d
\end{array}
\\\\\\
10=(40-4)u\implies \cfrac{10}{40-4}=u\implies \cfrac{10}{36}=u\implies \cfrac{5}{18}=u
\\\\\\
10=(40+4)d\implies \cfrac{10}{40+4}=d\implies \cfrac{10}{44}=d\implies \cfrac{5}{22}=d$

so, "u" is 16 minutes and 40 seconds.

and "d" is 13 minutes and about 38 seconds.
