Answer:

solve for x

x=2

Step-by-step explanation:

x2-20x-17=-53

reorder like terms x2= 2x 2x=20x-17=-53

collect like terms 2x-20x=-18x -18x-17=-53

move constant to the right hand side and change its sign -18x=-53+17

calculate the sum -53+17= -36 -18x=-36

divide both sides by -18 -18x÷-18= x -36÷-18=2

x=2

R = 850 cm, s = 250 cm and t=940 cm. Find the measure of ZS tothe nearest 10th of a degree

faust18 [17]

To find the measure of the s angle que are going use the cosine law because we know all the sides of the triangule:

s² = r² + t² - 2*r*t * cos(S)

Then solve the equation

s² -r² - t² = -2*r*t * cos(S)

arccos ((s² -r² - t² /-2*r*t)) = S

arccos (((250)² -(850 cm)²-(940 cm)² /(-2* 850 cm*940 cm) = S

14.9 = S

round to the nearest 10th of a degree

15º = S
