3.9
Step-by-step explanation:
It is rounded to 3.9 I think
Answer:
4t
Step-by-step explanation:
Let's form an equation here just to put it visually.
So it would be t+3*t
We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)
Now we can do t+3t which is 4t
If this doesn't make sense, then you can look at it this way
You do 1t+3t and since they're like terms, you can combine them and do 4t.
Answer:
<BAC = 78
<ABC = 68
Step-by-step explanation:
The remote angles theorem states that when one extends a side of a triangle, the angle formed between the extension and one of the sides of the triangle is equal to the sum of the two non-adjacent angles inside the triangle. One can apply this theorem here and state the following,
<BAC + <ABC = <ACD
Substitute,
(5y + 3) + (4y + 8) = (146)
Simplify,
9y + 11 = 146
Inverse operations,
9y + 11 = 146
-11 -11
9y = 135
/9 /9
y = 15
Now substitute this value back into the expressions to find the numerical measurement of (<BAC) and (<ABC),
<BAC = 5y + 3
5(15) + 3
78
<ABC = 4y + 8
4(15) + 8
68
