Answer:
yes
Step-by-step explanation:
6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.
Answer: yes
Also, you can reduce both fractions.
Divide the numerator and denominator of 6/12 by 6 to get 1/2.
Divide the numerator and denominator of 15/30 by 15 to get 1/2.
Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.
X = 47°
y = 90°
These are the angles, comment if you would like to know the explanation but these are the answers
Answer:
a) 3x - 11
b) 10x + 4
Step-by-step explanation:
a) The negative sign before the (x+5) means to subtract those values. Reverse the signs. Then combine like terms:
4x –6 –x –5. 4x–x–6–5
3x –11
b) Put all the x terms together.
Put all the integers together.
Add. Adding a negative is the same as subtracting.
4x+x+5x = 10x
+6-2 = 4
Combine them:
10x + 4
Angle O=64
Side m=7.3159882(rounded if needed)
Side n=16.68902(round if needed)
We are given
Angle M which equal 26.
Angle N equals 90 degrees
Side MN which equal 15.
We are asked to find all the missing elements of the triangle.
- Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.



Angle O=64 degrees
We can find side m by doing law of sines.



which is 7.315(round if neeeded).
We can find side n using pythagorean theorem,



Side n=16.689(round if needed)
