I will solve one for you to get you a idea so next u can solve all
To know whether line is tangent toa circle or not we should know that that line is a tangent line of a circle if it intersects circle at single point.
and this will always be perpendicular at radius
so in problem
1)
diameter is given 7.5
and u can see they make a right triangle ABC if that is perpendicular so segment AB is tangent to a circle.
Lets see by applying <span>Pythagorean Theorem
</span>this is method we can say that this is in fact a right triangle
a^2=b^2=c^2
a,b are shorter side c is longer side
(7.5)^2+(8)^2=(17)^2
56.25+64=289
120.25=289
both are not equal so they are not forming right triangle so segment AB is not a tangent line.

Answer:
C. 52°
Step-by-step explanation:
In ∆CAB, m<A = right angle = 90°
m<B = 38°
m<C + m<A + m<B = 180° (sum of ∆)
m<C + 90° + 38° = 180° (substitution)
m<C + 128 = 180
m<C = 180 - 128 (subtraction property of equality)
m<C = 52°
