What is measure of angle R?

krek1111 [17]

Given is a Right triangle PQR with angle Q = 90 degrees.

Given are sides PQ = 8 cm, QR = 15 cm, PR = 17 cm.

Side PR is the hypotenuse.

We can use formula for "sin" given as follows :-

$sin(\theta)=\frac{Opposite}{Hypotenuse}$

<u>For angle R, opposite side would be PQ. </u>

$sin(R)=\frac{PQ}{PR} \\\\ sin(R)=\frac{8}{17} \\\\ sin(R)=0.470588235 \\\\ R=sin^{-1}(0.470588235) \\\\ R = 28.07248694 \;\;degrees \approx 28.07 \;degrees$

<u>For angle P, opposite side would be QR. </u>

$sin(P)=\frac{QR}{PR} \\\\ sin(P)=\frac{15}{17} \\\\ sin(P)=0.882352941 \\\\ P=sin^{-1}(0.882352941) \\\\ P = 61.92751306 \;\;degrees \approx 61.93 \;degrees$

Hence, R = 28.07 degrees and P = 61.93 degrees.

Answer:

y = -¼│x − 5│+ 3

Step-by-step explanation:

y = a│x − h│+ k

(h, k) is the vertex of the absolute value graph. In this case, it's (5, 3).

y = a│x − 5│+ 3

One point on the graph is (1, 2). Plug in to find the value of a.

2 = a│1 − 5│+ 3

2 = 4a + 3

a = -¼

Therefore, the graph is:

y = -¼│x − 5│+ 3

Can someone PLZZZZ HELP!!!!

Answer:

The solution is:

Part A. $\sqrt{5}^{\frac{7k}{3}})$ which is sqrt(5)^7k/3[/tex]

Part B. k = 18/7

Step-by-step explanation:

Part A.

To solve this part, we're going two use THREE important properties of exponents:

1. $(x^{n})^{m} = x^{nm}$

2. $\frac{x^{n}}{x^{m}} = x^{n-m}$

3. $\sqrt[n]{x^{m}} = x^{\frac{m}{n} }$

Let's work the numerator using the properties 1, 2 and 3:

$(\sqrt{5}^{3} )^{\frac{k}{9} } } = (\sqrt{5}^{3\frac{k}{9}}) = (\sqrt{5}^{\frac{k}{3}})$

Let's work the denominator using the properties 1, 2 and 3:

$(\sqrt{5}^{6} )^{-\frac{k}{3} } } = (\sqrt{5}^{6\frac{k}{3}}) = (\sqrt{5}^(2k))$

Now dividing the numerator by the denominator:

$\sqrt{5}^{\frac{k}{3}-(-2k)})=\sqrt{5}^{\frac{7k}{3}})$

Part B

if $5^{\frac{3}{2} } 5^{\frac{3}{2}} = \sqrt{5}^{\frac{7k}{3}})$

Then:

$5^{3} = 5^{\frac{7k}{6}})$

So $\frac{7k}{6}} = 3$

Solving for k, we have:

k = 18/7
