<h2>Given :-</h2>
- Two adjacent angles of a parallelogram are in the ratio of 5 : 2.
<h2>To Find :-</h2>
- What is the all angles of the parallelogram.
<h3 /><h3 /><h2>Solution :-</h2>
Let, the first angles be 5x
And, the second angles will be 2x
As we know that,
★ Sum of all angles = 180° ★
According to the question by using the formula we get,
- ⇒
- ➠
Hence, the required angles are,
- First angles = 5x = 5(25.7°) = 128.5°
- Second angles = 2(25.7°) = 51.4°
As we know that,
opposite angles in a parallelogram
is equal.
∴ The all angles of a parallelogram is 128.5°,51.4°, 128.5° and 51.4°.
Answer:
23/8
Step-by-step explanation:
41.8, angle y and the measurement angle labeled as just "138.2" are supplementary angles, meaning that when you add them together they equal 180. So all you have to do is subtract 138.2 from 180 and you get your answer which is 41.8.
