Step-by-step explanation:
The central angles theorem states that the measure of an angle whose vertex is the center of the circle is equivalent to the arc surrounding it. One can apply this here by stating that the measure of the arc surrounding the (90) degree angle is (90) degrees.
The total degree measure of a circle is (360). Thus one can form an equation and solve it to find the measure of the arc surrounding the angle (b). Call the arc surrounding angle (b); ().

The peripheral angles theorem states that if the vertex of an angle formed between a tangent and a chord, is on the circumference (outer edge) of a circle, then the measure of the angle is equal to half of the measure of the surrouding arc. Please note that a chord is a line segment in a circle that intersects the circle in two points. A tangent is a line segment that intersects a circle at one point. One can apply this here by stating the following,

The answer would be 7 1/2 because you would add 1 1/2, 2 1/2,3 1/2 so there you go
The answer is seven in the last question you didnt say that the 2 was also a exponent. :) - beanz
Answer:
Your x angle here is supplementary to the missing angle of the triangle, the "missing angle" of the triangle is the same as <B - which is 75 degrees. So; to solve x, 180-75=x
x=105

Answer:
y = 26/7 or ≈ 3.71
Step-by-step explanation:
3y + 4y= 26
3y + 4y = 7y so,
7y = 26
Divide both side by 7, we got:
y = 26/7 or ≈ 3.71
Hope this helped :3
