Answer:

the answer is x=15 cm

Step-by-step explanation:

here the above given figure is a rectangle ABCD with diagonals AC and BD measuring AC= (x+10)cm and BD=(3x-20) cm

Now,

AC=BD

or, 3x-20 = x+10 [ diagonals of a rectangle are equal]

or, 2x = 30

or, x= 15 cm

I HOPE IT WILL HELP YOU!!!

SALARY In a recent year, the median salary for an engineer in the United States was $55,000 and the median salary for a computer

dalvyx [7]

Given :

Median salary of engineer , E = $55,000 .

Median salary of computer engineer , C = $52,000 .

To Find :

The total cost for a business to employ two engineers and three programmers for 1 year .

Solution :

Now , cost of paying two engineers .

$C_e=\$2\times 55000\\\\C_e=\$110000$

Also , cost of paying three programmers .

$C_p=3\times 52000\\\\C_p=\$156000$

Therefore , total cost for 1 year is $\$(110000+156000)=\$266000$ .

Hence , this is the required solution .
