Which one do you want me to answer?
x = 12
Step-by-step explanation:
From Pythagorean theorem,
x^2 + 9^2 = 15^2
or
x^2 = 225 - 81 = 144
x = 12
X = 66 degrees. (Co interior angles are supplementary, add up to 180)
2y + 4 = y + 7
2y - y = 7 - 4
Y = 3
+70 degrees above zero. That's the way I would write it. If it is in a sentence, it would be something like "Today's temperature was 70 degrees above zero. Terribly hot!! like a sauna." I'm thinking Centigrade when I make this statement. I don't think there's a place on earth that's ever recorded that temperature.
But you want an integer. So it is 70
Step-by-step explanation:
1/2 b×h that's the area
The answer is 7 square units
