Question

two adjacent angles of a rhombus are in the ratio 4:5 find all the angles of rhe rhombus ​

Answer 1

Step-by-step explanation:

Two adjacent angles of a parallelogram are in the ratio 4:5. Find their measures. Solution : Let the angles be 4x and 5x. Then, 4x + 5x = 180° 9x = 180° x = 20° So, angles are 4 × 20° = 80° and 5 × 20° =100°.
