Answer 1

since tangent and radius are perpendicular to each other,
angle Q = 90 degrees.
does that give you a hint?

Answer 2

sum of all angles in a triangle = 180 degrees

Answer 3

12+90=102
180-102=78

Answer 4

good!

Answer 5

Can you help me with another

Answer 6

sure

Answer 7

can you screenshot your question? i don't seem to be able to open that docx file.

Answer 8

AB is tangent to Oo. If AO =24 and BC=50 , what is AB

Answer 9

do you know about pythagoras theorem?

Answer 10

no

Answer 11

since AO and CO are both radius,
they both will be equal.

AO = CO = ..
and wo could have BO = BO + BC = ...

Answer 12

I meant

BO = BC +CO

Answer 13

70

Answer 14

AO=CO = 24
BC = BC + CO = 74

By Pythagoras theorem,
as tangent is perpendicular to radius,
\(AB^2+ AO^2 = BO^2 \)
\(x^2 + 24^2 = 74^2\)
find x
