Answer:
25. x = 17°
26. x = 50°
Step-by-step explanation:
25. There is a straight line which means :
108 +4x = 180
<em>so</em><em>l</em><em>v</em><em>i</em><em>n</em><em>g</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>o</em><em>b</em><em>t</em><em>a</em><em>i</em><em>n</em><em>e</em><em>d</em><em> </em><em>e</em><em>q</em><em>u</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em>
108+4x = 180
4x = 180 - 108
4x = 72
x = 72/4
x = 17°
26. Again we can see that the angles in which 101 and x + 29 exists is a straight line . which means :
101 + x + 29 = 180
101 + 29 + x = 180
130 + x = 180
x = 180 - 130
x = 50°
Answer:
t = 26
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
Step 2: Check if solution is correct.
Therefore, t = 26.
10. 3.1ft x3.14 = (your answer)
11. divide 18.84 by 3.14=(the diameter) then divide your diameter buy 2= (the radius)
