Answer:
144°, 144°, 36°, 36°.
Step-by-step explanation:
Take shorter angle = x
Then the bigger angle = 4x (4 times the other angle)
In a parallelogram, there are 4 angles. Also, in a parallelogram opposite angles are equal to each other.
So,
1 angle = x
2 angle = 4x
3 angle = x
4 angle = 4x
The sum of all 4 angles in a parallelogram = 360°. So,
4x + x + 4x + x = 360°
10x = 360°
x = 360/10
x° = 36°
4x = 36 × 4 = 144°
Angles in the parallelogram = 144°, 144°, 36°, 36°.

Step-by-step explanation:
4a^2+7ab-b^2
Step-by-step explanation:
Add the first two equations together:
3a^2-ab-2b^2
+ 2a^2+5ab-3b^2
---------------------------
5a^2+4ab-5b^2
Subtract that answer from the remaining trinomial:
5a^2+4ab-5b^2
- a^2-3ab-4b^2
--------------------------
4a^2+7ab-b^2
Answer:
Options (B) and (C)
Step-by-step explanation:
The given expression is 
By simplifying this expression,

= ![(\sqrt[8]{d})^{5}](https://tex.z-dn.net/?f=%28%5Csqrt%5B8%5D%7Bd%7D%29%5E%7B5%7D)
Option (B)
Similarly,

= 
= 
Option (C)
Therefore, Options (B) and (C) will be the correct options.
Step-by-step explanation:
2x (5x - 1) + (3x^2 - 7x - 2)
= 10x^2 - 2x + 3x^2 - 7x - 2
= 13x^2 - 9x - 2
a = 13
b = -9
c = 2
