If QR=13 and PT=8, FIND QT of the rhombus

evablogger [386]

Answer:

$|QT|=10.2$ units.

Step-by-step explanation:

The adjacent sides of a kite are equal.

$\Rightarrow |PQ|=13=|QR|$

Triangle PQT is a right triangle.

From the Pythagoras Theorem;

$|QT|^2+|PT|^2=|PQ|^2$

$|QT|^2+8^2=13^2$

$|QT|^2+64=169$

$|QT|^2=169-64$

$|QT|=\sqrt{104}$

$|QT|=2\sqrt{26}$

$|QT|=10.2$ units.

2^n-5×5^n-4=5

Papessa [141]

$\huge{\fbox{\sf{n=5 }}}$

Step 1:

$⇒ {2}^{n - 5} \times {5}^{n - 4} = 5$

Step 2:

$⇒{2}^{n - 5} \times {5}^{n - 4} = {5}^{1} \times {2}^{0}$

On comparing values we get:

Taking:

${2}^{n - 5} = {2}^{0}$

n-5=0

n=5✓

Taking:

${5}^{n - 4} = {5}^{1}$

n-4=1

n=5✓
