anygoal [31]3 years ago
6 0

Answer:

Step-by-step explanation:

Use the fact that C + 118 = 180       Subtract 118 from both sides

C + 118 - 118 = 180 - 118

C = 62

C + 57 = B          C and A are remote interior angles.  They equal the exterior angles that are not supplementary to B.

62 + 57 = B

B = 119

Please help with this problem
GrogVix [38]
The correct answer is B. 8<=l<=10. You can find this because we know the length is 2 feel more than the width, so when the length is provided, we can find the area. 8*6 is 48, which is the minimum area, and 10*8 is 80, which is the maximum area allowed.

Rachel deposited $200 into an account that earns 6% interest compounded twice a year for 10 years
Tanya [424]
<span>In order to calculate compounded interest, we use the formula: Final amount = initial amount x (increase rate)^(time periods). We know that the interest rate is 6%, so the factor we multiply by is 1.06. Moreover, the interest is compounded twice per year. This means that there will a total of 2 x 10 = 20 time periods over which the amount is compounded. Therefore, the final amount works out to be: Final amount = 200(1.06)^20, which is equivalent to $641.</span>

  • Hypotenuse² = sum of squares of other legs

that is ~

  • 15 {}^{2}  = 5 {}^{2}  +  {x}^{2}

  • 225 = 25 +  {x}^{2}

  • {x}^{2}  = 225 - 25

  • {x}^{2}  = 200

  • x =  \sqrt[]{200}

  • x = 10 \sqrt{2}

The correct choice is ~ B
