Answer:
No, 60 is the third interior angle's mesure, not the exterior ∠3.
Step-by-step explanation:
Say that ∠1=∠A=50 and ∠2=∠B=70. The remote interior angles are the angles that are not touvhing the exterior angle. So ∠3 would be the the exterior angle to ∠C. ∠C=60 as the sum of the interior angles is 180.
The exterior angle is the angle formed by extending one of the triangle's sides. A straight line has the angle 180, so∠3=180-∠C=180-60=120.
Answer:
220 seconds
explaination:
3 minutes is 180 seconds and 4/6 of a minute means 40 out of 60 seconds so 180 plus 40 is 220
Answer:12
Step-by-step explanation:
15^2-9^2=12^2
225-81=144
P(4) = 4(4) - 1
therefore, p(4)= 15
Answer: 8x + 14
Step-by-step explanation:
3x + 2 + 3x + 2 + x + 5 + x + 5 = 2(4x + 7) = 8x + 14
