Answer:
∠B = 54 °
Step-by-step explanation:
If sum of two angles add up to 180°, then the two angles are called supplementary.
m∠A + m ∠B = 180°
7x + 7 + 4x - 14 = 180
7x + 4x + 7 - 14 = 180
11x - 7 = 180
11x = 180 + 7
11x = 187
x = 187 ÷ 11
m∠B = 4x - 14
= 4*17 - 14
= 68 - 14
Answer:
10* 299.99=2999.9
2999.9/100=29.999
this would round up to 30, so Brittany saved $30. : )
Answer: 2.456 x 10 to the power 11
Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
