Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The 
and 
.
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.
The measure inscribed angle is half of the corresponding subtended arc.
AB is the tangent. So, 
because radius is perpendicular on the tangent and the point of tangency.
Therefore, 
and .
Angle of elevation would be 66 degrees
Answer: The common ratio is 4.
Step-by-step explanation:
Each term is four times the last term. The common ratio of a geometric sequence is the number that is being multiplied by each time to get the next term, which is four in this case.
Answer:
i just need the points
Step-by-step explanation:
Answer:
x = 2, y = 5
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, thus
PT = TR and QT = TS
Substitute in values
y = 2x + 1 → (1)
3y = 3x + 9 → (2)
Substitute y = 2x + 1 into (2)
3(2x + 1) = 3x + 9
6x + 3 = 3x + 9 ( subtract 3x from both sides )
3x + 3 = 9 ( subtract 3 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into (1)
y = 2(2) + 1 = 4 + 1 = 5
