Need now! solve for x.
a. 7
b. 1
c. 9
d. 12

the value of x is 9

Step-by-step explanation:

Tangent chord angle = half of intercepted arc

4x+19 = half of minor arc DE

Multiply by 2 on both sides

minor arc DE= 2(4x+19)= 8x + 38

sum of angle in a circle is 360 degree

minor arc DE + major arc DE = 360

Subtract 36 from both sides

Divide both sides by 36

x=9

0.02040816326

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
