Answer:
12 in.
Step-by-step explanation:
You have to use the Pythagorean theorem for this problem. Since we are solving for DE, we do:
5 squared + b squared = 13 squared
25 + b squared = 169
Isolate the b:
25 - 25 + b squared = 169 - 25
b squared = 144
Find the square root of 144 = <u>12</u>
<u>(The formula for the Pyathagorean theorem is a squared + b squared = c squared) </u>
Answer:
z = 48 :)
Step-by-step explanation:
z ÷ 4 = 12
So, all you need to do is multiply 12 by four, to get z- 48
hope this helped!
Answer:
x < 293 / 700
Step-by-step explanation:
−35x + 15 > 7/20
Multiplying all through by 20
-700x + 300 > 7
-700x > 7 - 300
-700x > -293
Divide all through by 700
- x > - 293 / 700
Multiply all through by -
x < 293 / 700
