Find the measure of angle CKJ if the measure of angle LKC is x + 96, the measure of angle LKJ is 131 degrees, and the measure of

svet-max [94.6K]

Answer:

The measure of angle CKJ is 44°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠LKJ=m∠LKC+m∠CKJ ----> by addition angle postulate

substitute the given values

$131\°=(x+96)\°+(x+53)\°$

solve for x

$131=2x+149$

$2x=131-149$

$x=-9$

<em>Find the measure of angle CKJ</em>

m∠CKJ=(x+53)°

substitute the value of x

m∠CKJ=(-9+53)=44°

* During a 10 year period, the number of people living in Sherbury increased by 5% to 20 265

eimsori [14]

Answer:During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942

Step-by-step explanation:

During the 10 year period,

Let x= increase in the number of

people living in Sherbury

y=number of people living in Sherbury before the increase

Therefore,

5/100 * y = x

0.05y=x

And

x + y = 20265

But y=20x

x + 20x =20265

21x=20265

x=965

During 10years ago the number of people living in Sherbury increased by 965.

Likewise

Let

a=increase in the number of

people living in Yaston

b=number of people living in Yaston before the increase

7.5/100 * b = a

0.075b = a

b=13.33a

a + b = 13502

a + 13.33a=13502

14.33a=13502

a=942

During 10years ago the number of people living in Yaston increased by 942.

Conclusion

During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942.

How do you solve this step by step?

SashulF [63]

ΔIJK ≈ ΔPQR => ∡I = ∡P =>

=> 3X + 4 = 72 - X

3X + X = 72 - 4

4X = 68

X = 68 : 4

X = 17
