Answer:
X=135 degrees
Step-by-step explanation:
the total interior angle of a triangle is 180.
To work this out you would first add the interior angles of B which is 69 and the interior angle of C which is 66, which gives you 135.
The next step is to minus 135 from 180, which gives you 45. This is because the total interior angle of a triangle is 180.
Then to work out the angle of x you would minus 45 from `180, which gives you 135. This is because the total angle in a straight line is 180 degrees.
1) Add the angles of 69 and 66.
2) Minus 135 from 180.
3) Minus 180 from 45.
Answer:
C
Step-by-step explanation:
using the cosine ratio to find p
cos 45° = =
cross- multiplying gives
p × cos45° = 6 → [ cos 45° = ]
p × = 6
multiply both sides by
⇒ p = 6 ( third option on list )
