Answer:
∠CAD = 44⁰
∠ACD = 44⁰
∠ACB = 136⁰
∠ABC = 22⁰
Step-by-step explanation:
To calculate m∠CAD;
Line AD = Line DC,
thus ∠CAD = ∠ACD = ¹/₂(180 - 92°) [sum of angles in a triangle.]
∠CAD = ¹/₂ x 88 = 44⁰
Also, ∠ACD = 44⁰
To calculate m∠ACB;
∠ACB = 180 - ∠ACD [Sum of angles on a straight line]
∠ACB = 180 - 44
∠ACB = 136⁰
To calculate m∠ABC;
Line CB = Line CA
Thus, ∠ABC = ∠CAB = ¹/₂(180 - ∠ACB) [sum of angles in a triangle.]
∠ABC = ¹/₂(180 - 136)
∠ABC = ¹/₂ x 44
∠ABC = 22⁰
Intersection, because they connect the lines. also they hold them together
Since the slope is falling, instead of rising, it would be negative.
Now, on the line, I plotted (0, 2) and (-2, 10).
You would now plug this into the rise/run formula.
The formula is
The equation would become,
=
=
-4I believe the answer would be
-4.
I hope this helps!
Answer:
Fourth option: x=1±√47
Step-by-step explanation:
This is a quadratic equation, then we must equal to zero: Subtracting both sides of the equation x², 5x, and 39:
Subtracting like terms:
Applying the quadratic formula:
Vertical angles therefore
100 = 21x -5
105 = 21x
x = 5
