2,605 rounded to the nearest hundred......now find the number in the hundreds place...it is the 6....now look at the number to the right of it...if that number is 5 or above, u round the 6 to a 7....but if that number is 4 or below, that 6 stays the same. The number to the right of 6 is 0.....so the 6 stays the same...and ur answer is 2,600.
The absolute value of b is equal to 7. Absolute value means the distance from zero. In simple terms, the positive version of the number. B could be 7 or -7, since both will be equal to 7 when you take their absolute value.
Answer:
64°
Step-by-step explanation:
Using Pythagoras rule :
Cosθ = adjacent / hypotenus
Adjacent = 167
Hypotenus = 381
Cosθ = 167 / 381
Cosθ = 0.4383202
θ = Cos^-1(0.4383202)
= 64.003
Hence, angle of elevation = 64°
Answer:
C
Step-by-step explanation:
They are both acute angles so the measurement cannot be above 90 degrees (right angle).
m<ADC is clearly smaller than m<AEC therefore m<AEC must be bigger than 28 degrees. C is the only option that fits
