Select all the properties of a non -square rectangle ? 3 Same -Side angles supplemental

Check Explanation

Explanation

Supplementary angles are angles that sum up to give 180 degrees.

And for all rectangles, whether a square one or non-square one, all of the angles of the rectangle are each 90 degrees.

So, it is clear that any two same side angles will be 90° + 90° = 180°

Meaning that same side angles of a non-square rectangle are supplemental.

Hope this Helps!!!

Can yah help me with those two question please
:(

Solution1:-

Statement : corresponding angles in similar triangles must be congruent .

Solution2:-

Statement : The hypotenuse of a right angle triangle has to be opposite of 90 degree .

Reason : We know that the side opposite to largest angle in a triangle is largest . Since in a right angle triangle 90 degree is the largest angle and hypotenuse is the longest side therefore they must be opposite to each other .

Steven wants to make some extra money using a CD account. He wants $22,000 in his account after 5 yearscompounded continuously. How much principal will he have to start with, at an interest rate of 6.625%? ### Answers Answer: You got to multiply 22,000 times 5 and that will equal 110,000 Step-by-step explanation: ### Final answer: To have a final balance of$22,000 in a CD account after 5 years with continuous compounding at an interest rate of 6.625%, Steven needs to initially deposit approximately $15,895.68. ### Explanation: To calculate how much principal Steven should start with in his CD account, we need to use the formula for continuous compounding, which is A = Pe^(rt), where: • A is the amount of money accumulated after n years, including interest. • P is the principal amount (the initial amount of money). • e is the base of the natural logarithm, approximately equal to 2.71828. • r is the annual interest rate (decimal). • t is the time the money is invested for in years. In Steven's case, he wants A =$22,000 after t = 5 years, at an interest rate r of 6.625% or 0.06625 in decimal format. Substituting these values into our formula and solving for P, we get:

P = A / e^(rt)

P = 22000 / e^(0.06625 * 5)

After calculating this expression, we find that Steven needs to deposit approximately $15,895.68 into his CD account to have$22,000 after 5 years with continuousinterest compounding at 6.625%.
