Answer:
The missing side has a length equal to 
Step-by-step explanation:
We need to find the length of the missing side on the right triangle. We were given the length of the hypotenuse, and the opposite cathetus, therefore we can use the sine relation. This is done below:

Add 1/5 and 1/3. 1/3+1/5=
First get common denominator( 15), So 5/15+3/15= 8/15
Then you calculate what is left over which is 7/15
Answer:
40 red, 48 yellow.
Step-by-step explanation:
So in your orange paint, the ratio of red paint to yellow paint is 2/3 : 4/5, we can simplify that to 2/3 (15) : 4/5 (15) ---> 10 : 12 ---> 5 : 6. So for every 5 parts of red paint, you need 6 parts of yellow paint. One part can be any amount, as long as all parts are equal. So together you need 5+6=11 parts. Lets divide 88 by 11 to get what one part is. 88/11=8, so in this case one part equals to 8 bottles. And remember you need 5 parts of red paint, so 5*8=40 bottles of red paint altogether, and 6 parts of yellow paint, so 6*8=48 bottles of yellow paint altogether to make your 88 bottles of orange pain.
Check: 40 bottles of paint + 48 bottles of paint will give you 88 bottles of paint in the end, so that is correct. 40 : 48 is also equal to 2/3 : 4/5 if you simplify them, so the ratio is also correct.
Answer:
80°
Step-by-step explanation:
Hello all triangles equal 180 degrees. So, with that being said to solve this you need to do 180-22-78 Which equals 80
