Answer:
a = 5
Step-by-step explanation:
3(a - 4) + 1 = 9 - a Distribute the 3 into a-4
3a - 12 + 1 = 9 - a Combine like terms
[-12 and 1]
3a - 11 = 9 - a Add 11 to both sides to isolate 3a
+11 +11
3a = 20 - a Add a to remove it and have all a
+a +a
4a = 20 Divide by 4 to only have a
/4 /4
a = 5
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
