Answer:
x=90 degrees
y=142 degrees
z=128 degrees
Step-by-step explanation:
Answer:
c = 14
Step-by-step explanation:
For this triangle we have to
We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
then
Now we use the sine theorem to find the length of c:
Therefore:
Answer:
x = -12
Step-by-step explanation:
-1/4x - 12 = x + 3
-x - 48 = 4x + 12
-x -4x = 12 + 48
-5x = 60
x = -12

Step-by-step explanation:
Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.
<h3>What are Supplementary Angles?</h3>
The sum of angles that are supplementary to each other equals 180 degrees.
Let the measure of the supplementary angle be x.
The other angle will be: x + 20.
(x + 20) + x = 180
x + 20 + x = 180
2x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80°
The other angle will be x + 20 = 80 + 20 = 100°.
The measure of the angles are: 80° and 100°.
