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:
N=6-2
Step-by-step explanation:
When speaking the language of math, "the same as" just means equal to. On the left side of the equal sign, you have your variable, and on the right is the rest of the equation. 6 reduced by 2 is the same thing as 6-2
Answer:
x= -4
Step-by-step explanation:
A line is 180 degrees. This means that we can use the equation
60+x+124=180
Simplify:
184+x=180
x= -4
We can check this answer by plugging it back in:
60 + (-4) +124 =180
180=180

Answer:
Slope m=2, y-intercept b=5 --> y=2x+5
Slope m=3, y-intercept b=5 --> y=3x+5
Slope m=5, y-intercept b=4 --> y=5x+4
Step-by-step explanation:
The slope number goes with x, and the y-intercept gets either added or subtracted from the end of the equation depending on weather it's positive or negative. (subtracted if it's negative and added if it's positive)
