a/5 + 6 = 10
Subtract 6 from both sides:
a/5 = 4
multiply both sides by 5:
a = 20
This is a isosceles triangle. all sides degrees added together (triangle) is equal to 180.
we know one side is 55°, and since its isosceles, it will be congruent on both sides. so there are 2 55°.
since the sum of all angles is 180°, the equation will be 55°+55°+x=180
combine like terms (55+55), which equals to 110.
last, 180-110 = 70
so the answer will be x = 70°

Answer:
x=25
x=47
y=25 x=10
y=20
Step-by-step explanation:
2x+10=60
-10 -10
2x=50
2x/2=50/2
x=25
2x+6=100
-6 -6
2x=94
2x/2=94/2
x=47
5y-25=100
+25 +25
5y=125
5y/5=125/5
y=25
11x-30+100=180
11x+70=180
-70 -70
11x=110
11x/11=110/11
x=10
7y-10=3y+70
+10 +10
7y=3y+80
-3y-3y
4y=80
4y/4=80/4
y=20
hopefully this helps :)
