Answer:
y = 2x - 5
Step-by-step explanation:
y - 3 = 2 (x - 4)
y = 2x - 8 + 3
y = 2x - 5
Answer:
first figure: y=70
second figure: Guessing that that number is 99, x=99, y=99, z=81
third figure: x=180-48-77=55 x=55
Step-by-step explanation:
To solve this problem, you must know that an inscribed angle equals 1/2 of the arc that it intercepts.
Therefore, because <ABC intercepts arc ADC, we know that
the measure of angle ABC = 1/2 * (measure of Arc ADC)
OR, when the values are substituted into the equation
165 = (1/2) (5)(x-3)
When simplified, this equation equals
330 = 5x - 15
345 = 5x
x = 69
Therefore, your answer is the second option, that x = 69 degrees.
Answer:
the triangle is a acute angle
