We can use two different methods to find our missing angle:
Subtract the two known angles from 180° :
Plug the two angles into the formula and use algebra: a + b + c = 180°
the answer is 33 because 3+3=6*10-35+2
Answer:
22x^2-9x+32
Step-by-step explanation:
(21x² - 6x +14) + (x²-3x+18)
To add, we need to combine like terms
21x^2+x^2 -6x-3x +14+18
22x^2-9x+32
Answer:
67 mm
Step-by-step explanation:
use area of a trap formula:
b1+b2 /2*h
b1=base
b2=base
h=height
in our case it was, 8.2+5.2/2*10
67
