Answer:
x = 12, y =
Step-by-step explanation:
a || b
5x - 7 = 3x + 17 Alternative Interior Angles
x = 12 Algebra
Angle 3x + 17 = 53 Substitution
53 + 4y + 3 = 180 Supplementary Angles
y = 31
8x4=32
32 divided by 2 = 16
the answer is 16 square feet
hope this helps :)
Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
83 1/3 % = 5/6 so
20 = (5/6)x
x = (6/5)(20) = 24
<h3>Calculate percentage of a number</h3>
For this, multiply 150 × .20 = 30
Therefore, 20% of 150 is 30.
- So, the correct option is "D".
