Step-by-step explanation:
Can you explain what you’re asking for
Answer:
(–1, 1)
(4, –2)
Step-by-step explanation:
Let
(x,y) ----> the coordinates of point C
Applying the Pythagoras Theorem
step 1
Find the possibles values of x
Simplify
Solve the quadratic equation
The values of x are
x=-1 and x=4
step 2
Find the possibles values of y
Simplify
Solve the quadratic equation
The values of y are
y=-2, y=1
therefore
The possibles coordinates of point C are
(-1,1),(4,-2)
Answer:
on the x-axis
Step-by-step explanation:
If x is less than 0, that means it's to the left of the origin, and if y = 0, then that means the point lies on the x-axis. Hence, (x,y) is on the x-axis.
Cheers.
Answer:
18°
Step-by-step explanation:
The law of cosines tells you ...
a² = b² + c² -2bc·cos(A)
Solve for cos(A) and fill in the numbers. Note that the value of cos(A) is very close to 1, so the angle will be fairly small. This by itself can steer you to the correct answer.
cos(A) = (b² +c² -a²)/(2bc) = (49 +100 -16)/(2·7·10) = 133/140
A = arccos(133/140) ≈ 18.2° ≈ 18°
