Answer:
60.0735651 degrees
Step-by-step explanation:
So the hypotenuse is 50 and the vertical leg is 13
For the angle, you need to find the sine (opposite and hypotenuse)
sin(x) = 13/50
x = asin(13/50)
x = 60.0735651
Answer:
193.75
Step-by-step explanation:
Perimeter r / perimeter s = side r/ side s
Perimeter r = 72 cm
Perimeter s = 36 cm
Side r = ???
Side s = 6 cm
72/36 = side_r/ 6 Cross multiply
72 * 6 = 36 * side_r
432 = 36 side_r Divide by 36
432 / 36 = side_r
12 = side_r
1 1/3 is simplified to 4/3
multiply 4/3 * 2/3 =8/9
3x+18+9x - 27 = 99
12x - 9 = 99
12x = 108
x = 9
m<PSQ = 3x + 18
m<PSQ = 3(9) + 18
m<PSQ = 27 + 18
m<PSQ = 45
answer
C. 45
