L = 3C ( Lacey sold three times as many calendars as Chris)
T = 5 + C (Talia sold 5 more calendars than Chris)
It also means that any angle that is not marked could be acute, right, or obtuse. For example, if this diagram appears without further comment
Answer:
155°
Step-by-step explanation:
In Δ ABC, let A = x°
By Angle-sum property,
A + B + C = 180°
But, it is given that C = 130°
So, x + B + 130 = 180
B = 180 - 130 - x
B = 50 - x
Since AD and BD are internal bisectors of A and B,
∠ DAB = x/2 and
∠ DBA =
In Δ ADB, by angle-sum property,
∠ DBA + ∠ DAB +∠ ADB = 180°
+ ∠ ADB = 180°
25 + ∠ ADB = 180°
∠ ADB = 180 - 25 = 155°
Hence, ∠ ADB = 155°
Lets use the distributive property to re-write this:-
18 + 36
2(9 + 18)
To make sure of this, lets solve
2*9 = 18
2*18 = 36
36 + 18 = 54
54 = 54 PERFECT
Answer: 2(9 + 18)
