1/2*5 = 2.5 ~ 3 (round-off)
1/3* 10 = 3.33 ~ 3
The answer is A because you can multiply 9 and 10 and find that -10 times -9 is 90 and it also adds up to -19 and then you rewrite it and factor
Answer:
See below in bold.
Step-by-step explanation:
1. The 3 angles in a triangle add up to 180 degrees.
So x = 180 - (55 + 25)
= 180 - 80
= 100 degrees.
2. The 4 angles in a quadrilateral add up to 360 degrees,, so
3x + 127 + 54 + 119 = 360
3x + 300 = 360
3x = 360 - 300
3x = 60
x = 20 degrees.
3. Exterior angle
= 94 + 42
= 136 degrees.
