the missing angle is 
° .
<u>Step-by-step explanation:</u>
Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :
We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c :
⇒ 
In question we have following parameters as :
Putting these value in we get :
⇒
⇒ 
⇒ 
⇒ 
⇒ °
Therefore , the missing angle is ° .
You can easily do just one step to get the value of x.
x + 9 =24 subtract 9 from both sides
x + 9 - 9 = 24 - 9
Simplify:
x = 15I hope I helped
you.
Answer:
the last option, 10,12,15
Step-by-step explanation:
for every 3 of something you have 5 of something else, so the ratio is 3:5. That means when you have 6, double the amount of 3, you have the double amount of 5, 10.
Answer:the number of BlackBerry that Arlene had initially was 276
Step-by-step explanation:
Let x represent the number of BlackBerry that Arlene had initially.
She gave 216 to her teachers. This means that she is left with x - 216
Then she dropped 12. This means that she would be left with x - 216 - 12 = x - 228
Later, she ate 18. This means that she would be left with x - 228 - 18 = x - 246
Finally, she gave half of what she had to her friend. This means that the amount that she gave to her friend is (x - 246)/2 and the amount that she has left would be
(x - 246)/2
Now, she has 15. This means that
(x - 246)/2 = 15
x - 246 = 2 × 15 = 30
x = 30 + 246 = 276
