Answer:
Step-by-step explanation:
By triangle sum theorem,
Sum of all angles of a triangle is 180°.
m∠1 + m∠2 + m∠3 = 180°
(m∠1 + m∠3) + m∠2 = 180°
2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]
2(m∠1) = 110°
m∠1 = 55°
Therefore, m∠1 = m∠3 = 55°
Answer:

Step-by-step explanation:
Write down the slope-intercept form:

Where m is the slope and b is the y-intercept.
To turn the equation into slope-intercept form, isolate y on the left-hand side:

Rearrange the equation a bit:

B, because 40 and 40 make 80 and 180-80=100<span />
Answer:
well 1 dozen is 12 so 12x50 is 600
