Answer:
x = 24
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + b^2 = 25^2
49 + b^2 = 625
<u>-49 -49</u>
b^2 = 576
square root them
b = 24, or x = 24

Answer:
first evening = 21 phone calls
second evening = 11 phone calls
third evening = 84 phone calls
Step-by-step explanation:
Total phone calls = 116
Let
Number of calls in the first evening = x
The second evening = x - 10
The third evening = 4x
Total phone calls = first evening + second evening + third evening
116 = x + (x - 10) + 4x
116 = x + x - 10 + 4x
116 + 10 = 6x
126 = 6x
x = 126 / 6
x = 21 phone calls
Number of calls in the first evening = x
= 21 phone calls
The second evening = x - 10
= 21 - 10
= 11 phone calls
The third evening = 4x
= 4(21)
= 84 phone calls

Answer:
CDJ= 34
Step-by-step explanation:
We know that ADJ = 90 degrees
ADK = 180 degrees and JDK equals 90 degrees so ADJ must equal 90 degrees
ADJ = ADC+CDJ
ADJ =4x+ 3x-8
Since ADJ = 90 degrees
90 = 4x+3x-8
Combine like terms
90 = 7x-8
Add 8 to each side
90+8 = 7x-8+8
98 = 7x
Divide each side by 7
98/7 = 7x/7
14 =x
We want to know CDJ
CDJ = 3x-8
CDJ = 3(14) -8
CDJ = 42-8
CDJ= 34
