Help!!!!!!!!!!!!!!!!!!!!!!!!!
torisob [31]

Answer:

53

Step-by-step explanation:

\frac{sin(56)}{78.6}  =  \frac{sin(90)}{ab}  \\  \\ absin(56) = sin(90) \times 78.6 \\  \\ ab =  \frac{sin(90) \times 78.6}{sin(56)}  \\ ab = 94.8 \\  \\  {x}^{2}   +  {78.6}^{2}  =  {94.8}^{2}  \\  {x}^{2}  =  {94.8}^{2}  -  {78.6}^{2}  \\  {x}^{2}  = 8987.04 - 6177.96 \\  {x}^{2}  = 2809.08 \\ x =  \sqrt{2809.08}  \\ x = 53

Stan invests $5000, some at 6% interest and the rest at 4.5% interest. If x is the amount he invests at 6%, then the amount inve
Bumek [7]

Geometry Help Please!!!<br><br> See Picture Below
MArishka [77]

Answer:

2. RS = ST, Reason: Midpoint of a line (definition)

4. RS = XY, Reason: Transitive Property of congruence (if a=b, and b=c, a=c)

Step-by-step explanation:

A Midpoint divides a line exactly in half, due to the definition of a Midpoint. So, RS = ST, since they measure the same distance from the Midpoint. RS=XY because of the Transitive Property of Congruence. If ST = XY, and RS = ST, then RS = XY.
