Sin (45o) = a / h = a / a sqrt (2) = 1 / sqrt (2) = sqrt (2) / 2 cos (45o) = a / h = a / a sqrt (2) = 1 / sqrt (2) = sqrt (2) / 2

tan (45o) = a / a = 1

csc (45o) = h / a = sqrt (2)

sec (45o) = h / a = sqrt (2)

cot (45o) = a / a = 1

answer: the value of x is 7cm

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
