Answer:
solution given:
m<a=m<c
3x+40=x+50
3x-x=50-40
x=10/2=5
now
<a=3×5+40=55°
m<a=55° is your answer
Step-by-step explanation:
<u>It is assumed the angles A and C are congruent:</u>
m∠A = 3*5 + 40 = 55°
answer is in the above picture
9514 1404 393
x1 = 1/2 + 1/2t
x2 = 4 -2t
x3 = t
Your answer is correct as far as it goes. The values of x1 and x2 also need to be expressed in terms of t.
