Answer:
44°
Step-by-step explanation:
8x - 4 = 6x + 8 (This is because they are corresponding angles)
8x - 6x = 8 + 4
2x = 12
x = 12 ÷ 2
x = 6
6x + 8 = angle 1 (Vertically opposite angles are equal)
Substitute the value of x in the equation '6x +8' to get the size of the angle.
6 × 6 + 8
36 + 8 = 44°
Angle 1 = 44°
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:
Next, now that we have the value of y, substitute it into either equation to solve for x:
<u>And this is how you get your final answer (5,2).</u>
Integers are whole numbers that can be negative or positive. Irrational numbers are numbers with repeating ends while natural numbers are positive whole numbers only. rational numbers are fractions. hence the answer to this problem is D.
Lisa is 50 years
Sam is 50 / 2 = 25 years
Brad is 25 * 3 = 75 years
For this case we have the following vectors:
u = (9, 0)
v = (0, -9)
Using product point we have:
u.v = (9, 0). (0, -9)
u.v = (9) * (0) + (0) * (- 9)
u.v = 0 + 0
u.v = 0
If the scalar product of two vectors is zero, both vectors are orthogonal.
Answer:
C. orthogonal
