The end points of diameter BD in a circle form an angle with point C. what is the measure of < BCD ? Is it A- 180 degrees?
B- 90 degrees?
C- 60 degrees?
Or D- 45 degrees?

And why?

I give Brainliest !

If BD is the diameter of the circle, and ∠BCD is an inscribed angle in the semicircle, then: B. m∠BCD = 90 degrees

Therefore, if BD is the diameter of the circle, and ∠BCD is an inscribed angle in the semicircle, then: B. m∠BCD = 90 degrees

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

answer: y = -2.5x - 15
