The legs of the drafting table form vertical angles. Find the measures of ∠1, ∠2 and ∠3.

m∡1 = 95°

m∡2 = 85°

m∡3 = 95°

Step-by-step explanation:

m∡1 + 85 = 180;   m∡1 = 95°

m∡2 = 85° because it is vertical and congruent to the angle measured 85°

m∡3 = m∡1 = 95° because they are vertical and congruent

1 = 95, 2 = 85, 3 = 95

Step-by-step explanation:

2 is an opposite angle of 85 degrees so 2 is 85 degrees

a line is always 180 degrees:

1 = 180 - 85 = 95 degrees

1 is an opposite angle of 3 so 3 is also 95 degrees

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
