7.

Supplement of an angle is four times of its complement find angle.please give answer step by step

Answer»

Answer:

Step-by-step EXPLANATION:

LET the angle be x

Let its compliment be y

Let its SUPPLEMENT be z

x+y=90

x+z=180

According to question

4y=z

x+4y=180

x=90-y

x=180-z=180-4y

90-y=180-4y

-y+4y=180-90

3y=90

y=90/3

y=30

x=90-y

x=90-30=60

Hence the angle is 60

Maths class 8 0.5y+5y/6 =21 +0.75y

Answer»

$Given \: simple \: equation :\\0.5y + \frac{5y}{6} = 21 + 0.75y$

/* MULTIPLY each TERM by 6 , we get */

$\implies 6 \times 0.5y + 6\times \frac{5y}{6} = 6 \times 21 + 6 \times 0.75y$

$\implies 3y + 5y = 126 + 4.5y$

$\implies 8y = 126 + 4.5y$

/* SUBTRACT bothsides by 4.5y , we get */

$\implies 8y - 4.5y = 126 + 4.5y - 4.5y$

$\implies 3.5y = 126$

/* DIVIDE each term by 3.5, we get */

$\implies \frac{3.5y}{3.5} = \frac{126}{3.5}$

$\implies y = 36$

THEREFORE.,

$\red { Value \: of \: y } \green { = 36}$

ANSWER:

X = 0.43

Step-by-step explanation:

1/3:1.3::1/9:X

1/3 × X = 1.3 × 1/9

X/3 = 13/10 × 1/9

X = 13/10 × 1/9 × 3

X = 13/10 × 1/3

X = 13/30

X = 0.433
