In parallelogram abcd, ab = 4x + 9, m∠bac = 5y + 1, m∠d = 75°, m∠acd = 56°, and cd = 45.   find the value of ‘x’ and ‘y’.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

c-   36
