so all angles of a triangle are going to add up to 180°
<u>so for L</u>
20 + 72 + x = 180
92 + x = 180
180 - 92 = 88
<u>For I</u>
56 + 89 + x = 180
180 - 145 = 35
<u>For C</u>
28 + 128 + x = 180
180 - 156 = 24
<u>For D</u>
122 + 38 + x = 180
180 - 160 = 20

hi
Step-by-step explanation:
x^2 - 3x + 9 - 5x + 10 = 0
x^2 - 8x + 19 = 0
