Find value of X . ROUND to the nearest tenth.

x = 8.1

Step-by-step explanation:

we see that it has (angle, adjacent, opposite)

well to start we have to know the relationship between angles, legs and the hypotenuse

α = 48°

a: adjacent  

o: opposite  = 6

h: hypotenuse  = x

sin α = o/h

cos α= a/h

tan α = o/a

if we see the sine it has the data that we have

sin α = o/h

sin 48 = 6/x

x = 6/sin 48

x = 8.07  

if we round to the nearest tenth

x = 8.1

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
