<em>If</em><em> </em><em>you</em><em> </em><em>only</em><em> </em><em>want</em><em> </em><em>to</em><em> </em><em>see</em><em> </em><em>the</em><em> </em><em>way</em><em> </em><em>i do</em><em> </em><em>it</em><em> </em><em>to</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>without</em><em> </em><em>seeing</em><em> </em><em>my</em><em> </em><em>explanation</em><em> </em><em>ignore</em><em> </em><em>sentences</em><em> </em><em>with</em><em> </em><em>symbol</em><em> </em><em>'</em><em>#</em><em>'</em>

<h2>Answer</h2>

•Pic on the left

x = 8.36

y = 140.18°

• Pic on the right

x = 110°

<h2>Way to do</h2>

• This one for the pic on the left

#Since the total degree of a triangle is 180° and one of the side known 90° (L) so the rest must be 90° (180° - 90° = 90°)

#known that the other side of triangle degree is (5x - 2)° and 6x° so... u can find the x! :D

90 = (5x - 2) + 6x

90 = 11x - 2

90 + 2 = 11x

92 = 11x

x = 92 : 11

x = 8.36 (2 decimal places)

#Now you know the x, you can now find the degree

#degree of (5x - 2)

5x - 2 =

5(8.36) - 2 =

41.81 - 2 = 39.81

#Since the y° is in the other side of the line of degre 39.81°, you can find it by minus it with 180° (straight line with no degree is 180°)

180° - 39.81° = 140.18

•This one for the pic on the right

#Lol this one is easy. I already told you before that the straight line degree is 180° and you can find one of the side if you know one of the degree side, so you can find it.

# Also as i said before, total triangle degree is 360°

#Find the degree of the other side of x° (only can find the degree of other side x because its inside the triangle)

Degree = 180° - 80° - 30° = 70°

#Now you can get x

x = 180° - 70° = 110°
