X = 60°
To work this out, you would do 50°+70° to get 120°. You would then subtract this from 180° (the total for any triangle) to get the final answer of 60°.
Answer: (-5x2 - 8x + 7) - (5x2 - 4)
Step-by-step explanation:
= -5x2 - 8x + 7 - 5x2 + 4
= -5x2 - 5x2 - 8x + 7 + 4
= -10x2 – 8x + 11
Answer: = (-5x2 - 8x + 7) - (5x2 - 4)
Answer:
B. 85
Step-by-step explanation:
A Triangle is 270 degrees so just add the two given numbers , subtract them from 27, and you get 85.
Answer:
C
Step-by-step explanation:
(c + 1)(c+1) = c² + c + c + 1 = c² + 2c + 1
That would be 10001 ( base 2) (answer)
This = 101 (base 4)
They both = 17 in decimal.
