157.	If a+b+c = 180,prove that
Answer» \|\|जय श्री कृष्णा\|\| Solution: Given that, A + B + C = 180 => B+C = 180-A LHS = tan[(B+C/2)] = tan[(180-A)/2] = tan(90-A/2) = cot(A/2) = RHS

157.

If a+b+c = 180,prove that

Answer»

||जय श्री कृष्णा||

Solution:

Given that, A + B + C = 180

=> B+C = 180-A

LHS = tan[(B+C/2)]

= tan[(180-A)/2]

= tan(90-A/2)

= cot(A/2)

= RHS

159.	Find the missing side.
Answer» $\huge{\underline{\underline{\bf{\pink{★Given}}}}}$ ◉ LENGTH of ladder, PR is 10m ◉ Length of ground, PQ is 6m ◉ Length of wall, QR is h ◉ PQ is horizontal and QR is vertical $\huge{\underline{\underline{\bf{\pink{★To \:find}}}}}$ ◉ HEIGHT of wall (QR) in meter. $\huge{\underline{\underline{\bf{\pink{★Solution}}}}}$ According to the given points, diagram is in a shape of right angled triangle. so, we use a formula to find our answer- $\huge{\underline{\underline{\bf{\blue{★Formula\: Used★}}}}}$ ${\underline{\sf{\red{[Pythagoras\: theorem => height ²\:+\:base² = \: hypotenious ²]}}}}$ [In the given PICTURE, QR is height, PQ is BASE and PR is hypotenious] ${\underline{\bf{\pink{Substituting\:values\:in\: theorem}}}}$ => height²+ base² = hypothesis² => h² + 6² = 10² => h² + 36 = 100 => h² = 100-36 => h² = 64 => h = √64 => h = 8m [Hence, height of wall ( QR) is 8m ] ✓

159.

Find the missing side.

Answer»

$\huge{\underline{\underline{\bf{\pink{★Given}}}}}$

◉ LENGTH of ladder, PR is 10m

◉ Length of ground, PQ is 6m

◉ Length of wall, QR is h

◉ PQ is horizontal and QR is vertical

$\huge{\underline{\underline{\bf{\pink{★To \:find}}}}}$

◉ HEIGHT of wall (QR) in meter.

$\huge{\underline{\underline{\bf{\pink{★Solution}}}}}$

According to the given points, diagram is in a shape of right angled triangle.

so, we use a formula to find our answer-

$\huge{\underline{\underline{\bf{\blue{★Formula\: Used★}}}}}$

${\underline{\sf{\red{[Pythagoras\: theorem => height ²\:+\:base² = \: hypotenious ²]}}}}$

[In the given PICTURE, QR is height, PQ is BASE and PR is hypotenious]

${\underline{\bf{\pink{Substituting\:values\:in\: theorem}}}}$

=> height²+ base² = hypothesis²

=> h² + 6² = 10²

=> h² + 36 = 100

=> h² = 100-36

=> h² = 64

=> h = √64

=> h = 8m

[Hence, height of wall ( QR) is 8m ] ✓

An estate value at $45,000 is divided among three girls in the ratio 7:10:13 calculate the amount each received.

Answer»

Step-by-step explanation:

1st girl RECEIVED

(45000*7)/(7+10+13)

= 10500$

2nd girl received

(45000*10)/(7+10+13)

= 15000$

3rd girl received

(45000*13)/(7+10+13)

= 19500$

PROVE that the ANSWER is correct

total =(10500+15000+19500)= 45000

ratio of value

10500: 15000: 19500

= 7: 10: 13
