Answer:
x = 154/13
Step-by-step explanation:
You are given the measures of all three angles in a triangle
so according to the Triangle Sum Theorem:
∠MNO + ∠OMN + ∠NOP = 180
1. Substitute the measures of the angles into the equation:
(3x + 11) + (2x + 20) + (8x - 5) = 180
2. Combine like terms:
(3x + 2x + 8x) + (11 + 20 -5) = 180
13x + 26 = 180
3. Isolate x by subtratcing 26 from both sides
13x + 26 -26 = 180 -26
13x = 154
4. Solve for x by dividing both sides by 13
13x/13 = 154/13
x = 154/13
A.)3(t + 19) = t – 7
B.)3(t + 7) = t – 19
C.)t + 19 = 3(t – 7)
D.)t + 7 = 3(t – 19)
Since the triangle is a right triangle, we can use the pythagorean theorem to solve for the one remaining side.
Plug in your values
a = 9
b = ?
c = 15
9^2 + b^ = 15^2. Square root 9 and 15
81 + b^2 = 225. Subtract 81 from each side.
b^2 = 144. Take the square root of each side.
b = 12.
Now we know the length and width of the rectangle.
Perimeter = 2(12 + 9)
Perimeter = 42 in
function below and determine if it is continuous or discrete.
