Step-by-step explanation:
Answer:
2a = 108
Step-by-step explanation:
the 3 angles of the triangle add to 180
lets call the unknown angle in the triangle y
a+10 + y + 44 = 180
we also know that 2a+ y = 180 because it makes a straight line
solve this for y by subtracting 2a from each side
2a +y = 180
y = 180 -2a
now we can substitute this into the triangle equation
a+10 + y + 44 = 180
a+10 + 180 -2a + 44 = 180
combine like terms
-a +234 = 180
subtract 234 from each side
-a = --54
divide each side by -1
a =54
the exterior angle is 2a
2* 54
108
Answer:
A) 15
Step-by-step explanation:
PEMDAS
20 / 4 + (6 * 2) - 2
take out the parenthesis which is P
20 / 4 + 12 - 2
there is no E
the go the rest of the way MDAS
5 + 12 - 2
17 - 2
15
Answer:
I believe it's B,hope this helps! :)
