Angles C and D are supplementary, meaning they add up to 180 degrees. So, if we add 8u-48 to 5u+46, we get 13u-2. We set that equal to 180, so 13u-2=180. Add the two, so 13u=182. Divide the 13, so u=14. To double check, plug in 14 to both expressions. 8(14)-48 and 5(14)+46. 8(14)-48 is 64. 5(14)+46 is 116. If you add 64+116, you get 180, which proves your answer right! So u= 14
If each blue tile has 5 sides and you know you have 3 blue tiles you can multiply 5 by 3
5 x 3 = 15 sides
Next you know the total number of sides is 30 and you just figured out that your 3 blue tiles have a total of 15 sides so you can subtract 15 from 30 to find how many sides are left
30 - 15 = 15sides
Since you know that these are not blue tiles because in the question it stated that you have 3 blue tiles. These have to be sides for red tiles.
Each red tile have 3 sides so you can divide 15 by 3
15/3 = 5
There are 5 red tiles
You are the number 5
Answer: " 874.33 ° " .
___________________________________
Step-by-step explanation:
15.26 rad * ( 180 degree /
rad ) ;
= [ (15.26 * 180) /
] degrees ;
= [ ( 2746.8 ) /
] degrees.
= [ ( 2746.8) / 3.14) ] degrees ;
= 874.3336 degrees;
→ round to: " 874.33 degrees ."

ANSWER: 56+8x
we know that
Applying the law of sines
b/sin B=c/sin C-------> solve for sin C
sin C=(c/b)*sin B-----> sin C=(36/19)*sin 36
sin C=1.1137-------> the value of the sines can not be greater than 1
The side lengths and angle given cannot be used to create a triangle
therefore
with the given values there is no solution to form some triangle
