2. Opposite sides of a parrallelogram are equal 2. Definition of parrallelogram
3. < D=<B 3. Definition of Parrallelogram
Answer:
first angle = 25 degrees
Second angle = 35 degrees
Third side = 120/degrees
Step-by-step explanation:
Let the size of the second angle be x degrees.
One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.
The measure of the third angle is
twice the sum of the measures of the first two angles. This means that
The third angle = 2( first angle + second angle). So the size of each angle is
First angle (x + 10) degrees
Second angle = x degrees
Third angle = 2(x + 10 + x) = (4x + 20) degrees
Sum of angles in a triangle = 180 degrees. Therefore, x + 10 + x + 4x + 20 = 180 degrees 6x + 30 = 180
6x = 180 - 30 = 150
x = 150/6 = 25 degrees
First angle = x + 10 = 25 +10 = 35
Third angle = 4x + 20 = 4 × 25 + 20
= 100+ 20 = 120 degrees

Answer:
Step-by-step explanation:
We start with the equation:
We want to find the value of:
We can start with our previous equation and multiply both sides by a:
Now we can rewrite our initial expression as:
Replacing that in the right side, we get:
Now again, let's multiply both sides by a
So we can conclude that:
Answer:
t = X - Xt - 1
Step-by-step explanation:
X=1+t/1-t
Multiply both both sides by 1 - t
X(1 - t) = 1 + t
X - Xt = 1 + t
t = X - Xt - 1
