Knowing about corresponding angles, we know that m∠d = 70°.

The sum of the measures of the angles d and g is equal to 180°. Or in other words, they are supplementary.

Knowing this, we can use algebra to build an equation and solve for g.

70° + m∠g = 180°
m∠g = 110°

And finally, using the knowledge of vertical lines, ∠g is complementary to ∠e.

So, m∠e is equal to 110°.

How do we find the breadth of square if perimeter and length is given

madreJ [45]

Answer:

A square has 4 sides of equal length, so if you have been given the length, this is also the breadth.

Therefore, the perimeter is 4 x side length.

For example, imagine a square with side length 3 cm. As all four side lengths are equal, the perimeter would be 4 x 3 cm = 12 cm

What is the answer to 10-(8p+3)=9(2p-5) ?

aniked [119]

Use distribution.
10 - (8p + 3) = 10 - 8p - 3 = 7 - 8p
9(2p - 5) = 18p - 45

So...
-8p + 7 = 18p - 45
Subtract 7 from both sides
-8p = 18p - 52
Subtract 18p from both sides
-26p = 52
Divide both sides by -26.
p = -2

There's your answer :D

8x+3x=8x+13/5 What value of 3x makes the equation true?

Mama L [17]

X=13/15. Subtract 8x from both sides to get 3x=13/5. Divide both sides by 3 or multiple both sides by 1/3 to get x=13/15.

100 points! Will mark brainliest! Only answer if u know it!

Svetlanka [38]

Step-by-step explanation:

Hey there!

The 1st equation is;

y= 1/2 x-8.............(i)

Comparing the equation y= mx+c. We get;

Slope (m1) = 1/2

The equation of point which moves through point (-3,-4).

(y-y1) = m2 (x-x1). {Use one-point formula to find out the equation}

(y+4) = m2 (x+3)..………(ii)

Now, we need to find m2.

So, the condition of perpendicular lines: m1*m2= -1.

$\frac{1}{2} \times m2 = - 1$

$m2 = - 2$

Therefore, m2 = -2.

So, let's keep value of m2 in eqaution (ii).

y+4 = -2(X+3)

y+4 = -2x-6

y = -2x -10.

Therefore, the eqaution is y= -2x-10.

Hope it helps......
