angle 3 is 140°

Step-by-step explanation:

angle 2 and angle 3 are equal

angle 4 and 1 are also equal

angle 3 =

180-40= 140

angle 3 is 140

see answer below.

Step-by-step explanation:

So m∠1= 40, as given in the question.

We should already know that a straight line, or angle, is equal to 180°

Knowing that it is equal to 180°, to find the angle of ∠3, you can subtract 40 from the 180°

180°-40°= 140°

m∠3= 140°

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117
