Answer:

mÐ4 = 30°

Step-by-step explanation:

Vertical angles are angles that are opposite to each other, thus are said to be equal.

Since,

i. Ð1 and Ð3 are vertical angles

ii. Ð2 and Ð4 are vertical angles

This implies that the measure of Ð1 and Ð3 are congruent. And also the measure of Ð2 and Ð4 are congruent.

So that, if mÐ2 = 30°, it would be expected that mÐ4 has the same measure. This implies that mÐ4 = 30°.

PLEASE ANSWER THIS ASAP, I WILL BE GIVING YOU A THANKS! .

Answer:

D.) 12

Step-by-step explanation:

16x - 3(4x + 5) = 2x + 9

16x - 12x - 15 = 2x + 9

4x - 2x = 15 + 9

2x = 24

2x/2 = 24/2

x = 12

Check:

16x - 3(4x + 5) = 2x + 9

16(12) - 3(4(12) + 5) = 2(12) + 9

192 - 3(48 + 5) = 2(12) + 9

192 - 3(53) = 24 + 9

192 - 159 = 33

33 = 33

What equation of the line that has a slope of -4 and passes through the point (-2,-5)? Answer ASAP!!

Anna11 [10]

Answer:

Given points are ( -2 , -5 ) and slope ( m) = -4

Step-by-step explanation:

y - y1 = m ( x - x1)

y + 5 = -4 ( x + 2 )

y + 5 = -4x - 8

4x + y +5 + 8 = 0

4x + y +13 = 0 

y = -4x - 13

which is the required equation
