What’s the answer for m

Archy [21]

Answer:

$m\angle D=35.5^o$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

Triangle CDE is an isosceles triangle

because

EC ≅ DE

therefore

$m\angle C=m\angle D$ ----> equation A

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle C+m\angle D+m\angle E=180^o$ ----> equation B

$m\angle E=109^o$ ---> equation C

substitute equation A and equation C in equation B

$m\angle D+m\angle D+109^o=180^o\\$

$2m\angle D=180^o-109^o$

$m\angle D=35.5^o$

If a line L has an equation Ax+By+C=0, what is the slope of L if B=0 an A does not equal O

Valentin [98]

If B=0, equation become Ax+C=0 or x=-C/A
since x is constant for the whole line, it is a vertical line, and the slope of L is ∞

The sum of two consecutive integers is 139, find the integers.

Ad libitum [116K]

They would be 69 and 70.

Your equation would be x + (x + 1) = 139

X would be the first integer and x + 1 would be the second

You would then solve the equation to get x as 69

X + 1 would then be 70
