Answer:
x = 17
Step-by-step explanation:
In order to make any sense of this problem, we must assume the lines that look parallel <em>are</em> parallel. With that assumption, the two marked angles are supplementary:
61° +7x° = 180°
7x = 119 . . . . . . . subtract 61°, divide by °
x = 17 . . . . . . . . divide by 7
Answer:
in a parallelogram .......the sum.of adjacent angles is 180
11x-10+80=180
11x=110
x=10

Step-by-step explanation:
Because 3x5 = 15 and 5x3=15 so it would be at 3 pm
Answer:
a² + 4ab + 4b²
Step-by-step explanation:
Given
(a + 2b)²
= (a + 2b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis
= a² + 2ab + 2ab + 4b² ← collect like terms
= a² + 4ab + 4b²
