Answer:
4.12
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
3. y + 1 = 4(x - 2)
4. y = 4x + 11
6. 8x - 2y = 6
This is a right triangle, the measure of angle A is 90 degrees.
First thing to do I guess is finding B and C.
tan^-1 (7/12) = 30 degrees
tan^-1 (12/7) = 60 degrees
60 + 30 = 90
180 - 90 = 90. Therefore angle A = 90 degrees
