Answer:
x = 71°
Step-by-step explanation:
The angles of any triangle will always amount to 180°.
Which means: (Angle of A) + (Angle of B) + (Angle of C) = 180°
Placing the known values into that equation will always let you know the third angle of any triangle.
(Angle of A) + (Angle of B) + (Angle of C) = 180°
(38°) + (71°) + (x) = 180°
109° + x = 180°
Solve for x by subtracting 109° from both sides
x = 180° - 109°
x = 71°
OR you can add the other two known angles 38° + 71° = 109°
This subtracted from the 180°
180° - 109° = 71°
Answer:
2.15 x 10^4
Step-by-step explanation:
since 21.5 is not between 1 and 10 we have to divide 21.5 by 10 which is 2.15 but now we have to x 10 to 10^3 which is 10^4

Answer:
The average change in temperature per hour was -8°F.
Step-by-step explanation:
Using the equation 48-(-16) we know that the temperature dropped by 64°F.
We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.
Therefore, the average change in temperature per hour was -8°F.
Answer:
$83.04
Step-by-step explanation:
1. Add up all the prices (49.99, 13,99, 13.99) = 77.97
2. Tax is 6.5% (.065 in decimal form)
3. Multiply 77.97 * .065 = 5.06805
4. 5.06805 rounds to 5.07
5. Add the total purchase (77.97) to the tax (5.07) = 83.04
