W = the woman's age
m = michael's age
8m = w
15(m -2) = (w-2)
15(m - 2) = (8m - 2)
15m - 30 = 8m - 2
15m - 8m - 30 = 8m - 8m - 2
7m - 30 = -2
7m - 30 + 30 = -2 + 30
7m = 28
m = 4
8m = w
8(4) = w
32 = w
w = 32 years old
m = 4 years old
And the answer is : 4m+m=180.
Do hope you will find it helpful!
Step-by-step explanation:
m<SMJ + m<SME = 180° <em>(Linear pair) ⇒ </em>m<SMJ + 59° = 180° ⇒ m<SMJ = 121°
m<MJS ≅ m<EJA: <E + <A + <J = 180° ⇒ 90° + 48° + <J = 180° ⇒ <J = 42°
<u>m<JSM + m<SMJ + m<MJS = 180° </u><u><em> (Triangle sum) </em></u>
m<JSM + 121° + 42° = 180°
m<JSM + 163° = 180°
m<JSM = 17°
Answer: 17°
The equation for slope between two points is (y1-y2)/x1-x2
Plug the points into the equation
-5-(-10)/-2-3
5/5
m=1
To find the equation, use y-y1=m(x-x1)
y-(-5)=1(x-(-2))
y+5=x+2
y=x+2-5
y=x-3
