Answer:
Step-by-step explanation:
Since a scalene, K would be 45. So 45+45+x=180
90+x=180
x=90
sin(x) = ⁴/₅
sin⁻¹[sin(x)] = sin⁻¹(⁴/₅)
x ≈ 53.13
cos(90 - x) = cos(90)cos(x) + sin(90)sin(x)
cos(90 - 53.13) = cos(90)cos(53.13) + sin(90)sin(53.13)
cos(36.87) = 0cos(53.13) + sin(53.13)
cos(36.87) = sin(53.13)
cos(36.87) = cos(90 - 53.13)
cos(36.87) = cos(36.87)
Answer:
9x +5

combine like terms!
Answer:
h = 6.7
Step-by-step explanation:
sin(48) = 5/h
so
h = 5 / sin(48)
h = 5 / 0.7431
h = 6.7
Answer:
$275.10
Step-by-step explanation:
$262.00 x 5% = $262.00 x 0.05 = $13.1 = $13.10
$262.00 + $13.10 = $275.10
