Answer:
(2.8 x 10^8) / (7 × 10^2) = 400'000
Step-by-step explanation:
Answer:
Adding the 2 known angles: 60° + 100° = 160° We subtract this from 180°. 180° – 160° = 20°. Our missing angle is 20°. To find a missing angle in a triangle we subtract the two known angles from 180°.
Step-by-step explanation:
Answer:
24X58-9=1,383
800x24=19,200
Step-by-step explanation:
24x58=(24x8)+(24x50)
24x8=160+32=192
24x50=200+1,000=1,200
192+1,200=1,392-9=1,383
800x24=3,200+16,000=19,200
Answer:
x = 4
Step-by-step explanation:
Answer:
40, 60 and 80 degrees.
Step-by-step explanation:
Let the smallest angle be x degrees. Then:
The 3 angles are x, x + 40 and x + 20.
As there are 180 degrees in a triangle:
x + x + 40 + x + 20 = 180
3x = 180 -40--20 = 120
x = 40 degrees.
The other 2 angles are 60 and 80 degrees.
