Answer:
25
Step-by-step explanation:
ABC is a right angle so ABD and DBC are <em>complementary angles</em> and their sum is equal to 90:
x + 55 = 90 subtract 55 from both sides
x = 25
Answer:
(2, 6)

Answer:
The above system of equation have NO INTERSECTION POINT.
Step-by-step explanation:
Here, the givens system of equation are:
-3 x + 3 y = 4
and y = x + 3
Now, for the intersection of the equations:
Put y = x + 3 in the given first equation:
-3 x + 3 y = 4 ⇒ -3x + 3 (x+ 3) = 4
or, - 3x + 3x + 9 = 4
⇒ 9 = 4 which gives A CONTRADICTION as 9 ≠ 4
Hence, the above system of equation have NO INTERSECTION POINT.
