Answer:
D = 98
Step-by-step explanation:
if you add up 59 + 39 you get 98 meaning D is 98
Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)
The answer would be the first one
Answer:
(x + 5) /2
Step-by-step explanation:
"a number" (this will represent as "x")
"increased" another way to say add or "+"
then divided by 2
If you wrote it out like this "x+5/2"it would be wrong because of PEMDAS making you want to divide first instead of after.
