130 degrees.
ADB = 90 degrees
BDT=40 Degrees
Therefore, TDS = ADB(90)+BDT(40)=130 degrees
10 sides
360-72=288
288 divided by 2 is 144
Decagon have 144 degree interior angles
I’m assuming you man degrees? Are these angles of a triangle?
This doesn’t really make sense because the angles in a triangle add up to 180° so your equation would be x+50+x+80+72=180
Combine like terms to get
2x+202=180
Then subtract 202 from both sides
2x=-22
So x would be -11 which doesn’t seem right lol
Answer:
It is not proportional
Step-by-step explanation:
To figure out if something is proportional they have to equal the same thing.
As you can see on the problem 0.2 and 0.2 are the same thing, and since one is on the numerator and one is on the demoninator those two can cross out.
Now we come to the 0.08 and the 0.8.
They are not the same thing the 0.08 has an extra 0.
So this is not proportional
