Answer:
1. The measure of ∠WOV is 60°. You would use complementary angles that are adjacent (∠WOV, and ∠XOW)
2. The measure of ∠YOZ is 60°. You would use the vertical angles that are non-adjacent (∠WOV, and ∠YOZ). These two angles are congruent so they would have the same measure. These angles combined also create supplementary angles
3. Another way to find the measure of ∠YOZ would be to make/write an equation and solve for x. For example, (3x+30)°=60°. x would equal 10 because 10x3=30+30=60°
Step-by-step explanation:
1. Since a complementary angle would equal 90°, simply subtract 30° from 90° resulting in 60°.
2. Because vertical angles are congruent and (∠WOV, and ∠YOZ) are a pair of them, they equal the same as each other so they're both 60°.
3. You can make any equation with x included as long as it equals 60° mine was just an example you can make your own like 10x+10=60 or 4x+20=60. Also to create your equation you also need to use the angle fact of the vertical angles
Answer: 10.7 years.
Step-by-step explanation:
7,300 * (1 + 0.015)^x = 8,560 <=>
7,300 * 1.015^x = 8,560 <=>
1.015^x = 8,560 / 7,300 <=>
1.015^x = 1.1726 <=>
x = 10.694
To the nearest tenth:
x = 10.7 years
Answer:
Neither
Step-by-step explanation:
When you rearrange the equation 3x+2y=1 in the form of y=mx+c
you get:
2y=-3x+1
And if you compare it with the equation y= -x -1
You can see that the gradient is not the same, so it means it is not parallel.
To get if it is perpendicular you need to see if the two gradients multiply to give the value -1 but when you multiply
×
so it is not perpendicular as well
I hope it is right, feel free to point out anything wrong or you're unsure of :)

a)
Let's just use Pythagoras
L² = X² + (X - 7)²
<h3>L = √(2X² - 14X + 49)</h3><h3 />
b)
If L = 13, then what is the value of X ???
L² = 2X² - 14X + 49
2X² - 14X - 120 = 0
X = 12 or X = - 5
<em>(The distance cannot be negative, so X = 12)</em>
