Two angles are supplementary the first angle measures 30 what’s the measurement of the second angle?

agasfer [191]

I believe it is 150º because a supplementary angle is 180º so 180-30=150.

Answer:

x = 8

Step-by-step explanation:

$\sf If\:\: \overline{NO} \parallel \overline{KJ}\:\:then\:\: \triangle LNO \sim\triangle LKJ$

Therefore:

$\implies \sf \overline{LN} : \overline{LO} = \overline{LK} : \overline{LJ}$

$\implies (x-3):(x-4)=(x-3)+(x+2):(x-4)+x$

$\implies \dfrac{x-3}{x-4}=\dfrac{2x-1}{2x-4}$

$\implies (x-3)(2x-4)=(2x-1)(x-4)$

$\implies 2x^2-10x+12=2x^2-9x+4$

$\implies -10x+12=-9x+4$

$\implies 12=x+4$

$\implies x=8$

I neeeeed help with these 2 pleaseeee pleaseeee help

goldfiish [28.3K]

Answer:

Question 8: 8.94

Question 9: 8.94

Step-by-step explanation:

Question 8: Using pythagorean theorem [a^2+b^2=c^2], we do (8*8)+(4*4) getting 80 which is our c^2. Now we find the square root of which is 8.94.

Question 9: Using pythagorean theorem [a^2+b^2=c^2], we do (5.3*5.3)+(7.2*7.2) getting 79.93 which is our c^2. Now we find the square root of which is 8.94.

Please correct or msg me if this is wrong.

Find the sum of the numbers divisible by 7 between 30 and 500

brilliants [131]

Answer:

17822

Step-by-step explanation:

The number that are divisible by 7 between 30 and 500 are as follows :

35, 42,49,.....,497

It will form an AP with first term, a = 35 and common difference, d = 7

Let there are n terms in the AP.

nth term of an AP is given by :

$a_n=a+(n-1)d$

Putting all the values,

$497=35+(n-1)7\\\\462=(n-1)7\\\\n-1=66\\\\n=67$

Now, the sum of n terms of an AP is given by :

$S_n=\dfrac{n}{2}[2a+(n-1)d]$

Putting all the values,

$S_n=\dfrac{67}{2}[2(35)+(67-1)7]\\\\S_n=17822$

Hence, the sum of the numbers that are divisible by 7 between 30 and 500 is 17822.
