square, anddddddddddddddddd deskkkkkk I thinkjkkkkk
Might be late but the first one is 125 and the seced one is less than :)
For this case we have the following equation:
an = a1 + (n - 1) • d
Where,
a1 = 57
d = 66-57 = 9
For the term number 250 we have:
n = 250
Substituting the values:
a250 = 57 + (250 - 1) * 9
a250 = 2298
Answer:
D.2298
The value of x in the angle ABC is 25.
<h3>How to find the angles in circle?</h3>
The measure of an inscribed angle is half the measure of the arc intercept.
In other words, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
Hence, lets find the value of x in the angle ABC.
Therefore,
m∠ABC = 1 / 2 (arc AC)
arc AC = 76 degrees.
Hence,
m∠ABC = 1 / 2 × 76
2x - 12 = 1 / 2 × 76
2x - 12 = 38
add 12 to both sides of the equation
2x - 12 = 38
2x - 12 + 12 = 38 + 12
2x = 50
divide both sides by 2
2x / 2 = 50 / 2
x = 25
