What is the value of M
Serggg [28]

m∠a = 56°, m∠b = 34°, m∠c = 56°

Solution:

<em>Sum of the adjacent angles in a straight line is 180°.</em>

⇒ m∠a + 124° = 180°

⇒ m∠a = 180° – 124°

⇒ m∠a = 56°

∠a and ∠c are vertically opposite angles.

Vertical angle theorem:

<em>If two lines are intersecting, then the vertically opposite angles are congruent.</em>

⇒ ∠a ≅ ∠c

⇒ m∠a = m∠c

⇒ m∠c = 56°

<em>Sum of the adjacent angles in a straight line is 180°.</em>

m∠b + 90° + m∠c = 180°

m∠b + 90° + 56° = 180°

m∠b + 146° = 180°

m∠b = 180° – 146°

m∠b = 34°

Hence m∠a = 56°, m∠b = 34°, m∠c = 56°.

1) The perimeter of a rectangular classroom floor is 90 feet. The length of the floor is twice the
lana [24]

Answer: The equation would NOT help us solve for the length and width of the classroom is "x + 2y = 90".

Step-by-step explanation:

Let y be the width of the rectangular classroom floor and x be the length of the rectangular classroom floor .

Given ,

The perimeter of a rectangular classroom floor is 90 feet.

The length of the floor is twice the  width.

i.e. Length =2 (width)

i.e. x= 2y ..(i)

Also, perimeter = 2(length+width)

i.e. 2(x+y)=90\\\\\Rightarrow\ 2x+2y=90

When we put value of x from (i), we get

2(2y) + 2y = 90

Hence, the equation would NOT help us solve for the length and width of the classroom is "x + 2y = 90".
