We can find m∠BCD like follows: m∠BCD=90°-45°=45<span>°
Now, m</span><span>∠DBC= 180°-(90°+45°)=45°
Remember that </span>

, so

We know that hypotenuse= BC= 3in and

=∠DBC)=45°, so replacing the values we get:

We can conclude that the segment CD is 2.12 in
Answer:
<u>20%</u>
Step-by-step explanation:
520,000/650,000 = 0.8
Sold for 80% of original price
Lost percent = 100% - 80%
20%
Answer:
500/50, 600/60, 700/70
Step-by-step explanation:
500/50 equals 10 and so do the others. This is because the fraction line means division.
Have a nice day!!!!!! :-)

The larger number is 13 and smaller number is 4
<em><u>Solution:</u></em>
Let the larger number be "a"
Let the smaller number be "b"
<em><u>Given that larger of two numbers is twice the smaller increased by five</u></em>
larger number = twice the smaller increased by five
larger number = twice the smaller number + 5
a = 2b + 5 --- eqn 1
<em><u>Also given that three times the larger exceeds double the smaller by 31</u></em>
Here "exceeds" denotes addition and "times" denotes multiplication
"double" denotes being multiplied by 2
three times the larger number = double the smaller number + 31
3a = 2b + 31 ---- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "b"</u></em>
Substitute eqn 1 in eqn 2
3(2b + 5) = 2b + 31
6b + 15 = 2b + 31
6b - 2b = 31 - 15
4b = 16
<h3>b = 4</h3>
From eqn 1,
a = 2b + 5
a = 2(4) + 5
a = 8 + 5
<h3>a = 13</h3>
Thus the larger number is 13 and smaller number is 4
