Sum of interior angles of a △ = 180°
∴ ∠T + ∠V + ∠U = 180°
⇒ 37° + 63° + X° = 180°
⇒ X° + 100 = 180°
⇒ X° = 180° - 100°
⇒ X° = 80° (D).
400+30+7. +0+4
3,000,000+500+40+3,000+2+1
All of those are true, except the one about the radius. Because alternate definition of diameter uses the idea of chord. So, both ends of a chord have to be on the circle, but one end of a radius is at the center, so a radius can't be a chord.
So you would need to add:
500$ + 80$ + 175$ = 755$
Since John paid 900$ then you would subtract how much he is buying it for from how much Davis spent to fix it
900$ - 755$ = 145$ (on profit Davis earned)
Answer:
4 mechanical pencils
Step-by-step explanation:
Each notebook is worth $2.99
So buying 3 of the notebooks would leave her with $8.97
Then, $15.00 - $8.97= $6.05
