See the picture attached to better understand the problem
we know that
A quadrilateral is called Cyclic quadrilateral <span>if its all vertices lie on the circle.
</span><span>The opposite angles of a Cyclic - quadrilateral are supplementary
</span>so
∠A+∠C=180°
and
∠
B
+∠D=180°
therefore
the answer is<span>
C) The sum measure of ∠B and ∠D equals 180°</span>
a possible answer would be 36/9=4
Answer:
c
Step-by-step explanation:
im a math genius
<span>To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- There are 75 classmates.
- 56% of his 75 classmates like salsa music and 80% of his 60 relatives like salsa music.
2. Therefore, you have:
- Number of his classmates that likes salsa music:
75x0.56=42
- Number of his r</span>elatives that like salsa music:
60x0.80=48
3. Then you have:
48-42=6
Therefore, the answer is: 6.
The correct answer is A.
Here is the completed problem:
3(4x+5)=12
Distributive property.
3(4x+5)=12
Simplify
12x+15=12
Subtract 15 from both sides.
12x+15−15=12−15
12x=−3
Divide both sides by 12.
12x/12 = −3/12
x= −1/4
