5*9=45
1*9=9
Then add both numbers together
45+9=54
Answer:
see below
Step-by-step explanation:
1. < 4 is the exterior angle of a triangle given
2. <1 + <2 + <3 =180 basic property of triangles
3. <3 + <4 are a linear pair <3 and <4 are adjacent and form a straight line
4. <3 and <4 are supplementary angles supplementary angles are linear pairs
5. <3 + <4 = 180 The definition of supplementary angles are that they add to 180 degrees
6. <1 + <2 + <3 = <3+ <4 Substitute <3 + <4 for 180 in equation from step 2
7 <1 + <2 = <4 Subtract <3 from each side using the subtraction property of equality
104 and 105 are consecutive numbers that add up to 209. Maybe this answers your question? Let me know otherwise.
Answer:
Step-by-step explanation:
We need to simplify
We collect LCM to get;
Therefore:
Also we need to simplify:
We collect LCM to get;
Therefore
The answer is C.0,3 because One of Y equal 0 for X
