Every triangle equals 180 degrees, and we're trying to find the angle of DBA. So, we can identify DAB as a 90 degree angle to start. Then we can identify that ACB = ADB, meaning ADB is 30 degrees. With that information, we have this equation:
DBA = 180 - 90 - 30
DBA = 60
Answer:
120
Step-by-step explanation:
To estimate the value, you round the digits to the nearest 10 , or the nearest 2 significant figures, in this case, 40.16 is rounded to 40 and 2.970201 is rounded to 3. This gives us 40 * 3 = 120
I agree because when you multiply a positive number such as 1/10 by any negative number the result will always be negative.
Answer: Rounded it would be 0, unrounded it would be 0.0144927536231884

Answer:
47°
Step-by-step explanation:
so a straight line is 180°
It gives us 82° for line D, so to find angle C, we must do 180° - 82° = 98 °
Hopefully you know that a triangle is also 180°
we know two angles: 35, 98
35° + 98° = 133°
180°-133°= 47°
47° is angle B
