1+Sin/Cos + Cos/1+Sin = 2Sec

Bond [772]

Step-by-step explanation:

Consider the left-hand side:

$\dfrac{1+\sin{\theta}}{\cos{\theta}} + \dfrac{\cos{\theta}}{1+\sin{\theta}}$

$\:\:\:\:= \dfrac{(1+\sin{\theta})^2 + \cos^2{\theta}}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:=\dfrac{1+2\sin{\theta}+\sin^2{\theta} + \cos^2{\theta}}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:=\dfrac{2+2\sin{\theta}}{\cos{\theta}(1+\sin{\theta})} =\dfrac{2(1+\sin{\theta})}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:= \dfrac{2}{\cos{\theta}} = 2\sec{\theta}$

Naddik [55]

Answer:

215d + $2500

Step-by-step explanation:

Amount paid for food booth

15*$100 + 15*d*$5 = 75d + $1500

Amount paid for game booth

20*$50 + 20*d*$7 = 140d + $1000

Total amount paid

75d + $1500 + 140d + $1000 = 215d + $2500

The quadrilaterals JKLM and PQRS are similar.

Sveta_85 [38]

Answer:

$x$ = 2.8

Step-by-step explanation:

If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:

KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7

JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7

LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7

This shows that the ratio of KJ : QP = 5/7

KJ : QP = 2 : $x$ = 2 / $x$

Therefore, $\frac{2}{x}=\frac{5}{7}$

cross multiply: 14 = 5 $x$

Divide both sides by 5: $x$ = 2.8
