Answer:

∠C = 159°

∠D = 21°

Explanation:

∠C + ∠D = 180 (1)

∠C = 33 + 6∠D (2)

Substituting (2) to (1):

180 = 33 + 6∠D + ∠D

= 33 + 7∠D

180 - 33 = 7∠D

147 = 7∠D

21 = ∠D

If ∠D = 21,

∠C + 21 = 180

∠C = 180 - 21

∠C = 159

Suplementary is angles add up to 180 degrees

C=180-D

C=180-84

C=96 degrees

Hope this helped :)

what is the equation in slope intercept form of the line that goes through (2,4) and is perpendicular to the line represented by

Andrej [43]

Answer:

$y = \frac{3x}{2}+1$

Step-by-step explanation:

The slope-intercept form of a straight line equation is y = mx + c, where m is the slope and c is the y-intercept of the line.

Now, we know that if two straight lines are perpendicular to each other then the product of their slopes will be -1.

So, the equation of a straight line which is perpendicular to the line $y = -\frac{2x}{3} +6$ will be $y= \frac{3x}{2}+ c'$ ....... (1), where c' is constant.

Given that the line (1) passes through (2,4) point.

Hence, $4 = \frac{3(2)}{2} +c'$

⇒ c' = 1.

Therefore, the final equation of the required straight line is $y = \frac{3x}{2}+1$ . (Answer)

Why is estimation an important tool ??

forsale [732]

Estimation is a way to find out the approximation of something. It is important because it kinda leads to what the correct answer is and it is needed because you can estimate how much a bill would be or you could estimate how much is the area or size of something. It's very important...
