If m<SDN=5x-2 and m<DNA=3x+4.
a. Find m<SDN
b. Find m<DSA
If angles <𝟏 𝐚𝐧𝐝 <𝟐 are corresponding, or alternate interior, or alternate exterior, then they are equal, hence their measures are equal
thus;
"\ud835\udfd1\ud835\udc99 + \ud835\udfd2 = \ud835\udfd3\ud835\udc99 \u2212 \ud835\udfd0"
"\ud835\udfd0\ud835\udc99 = \ud835\udfd4"
"\ud835\udc99 = \ud835\udfd1"
If angles ⦟𝟏 𝐚𝐧𝐝 ⦟𝟐 are consecutive interior angles, then they add up to 𝟏𝟖𝟎° , hence
"3\ud835\udc99 + \ud835\udfd2 + \ud835\udfd3\ud835\udc99 \u2212 \ud835\udfd0 = \ud835\udfcf\ud835\udfd6\ud835\udfce"
"\ud835\udfd6\ud835\udc99 + \ud835\udfd0 = \ud835\udfcf\ud835\udfd6\ud835\udfce"
"\ud835\udfd6\ud835\udc99 = \ud835\udfcf\ud835\udfd5\ud835\udfd6"
"\ud835\udc99 = 113\u00b0\ud835\udfcf\ud835\udfd3'\n."
a)
m<SDN = "5x+2"
m<SDN = "5 \\times 22.25 +2"
m<SDN = 𝟐𝟐°𝟏𝟓'
b)
m<DSA = "3x+4"
m<DSA = "3\\times22.25 + 4"
m<DSA = 70°4𝟓
