Answer:

y = 120º

Step-by-step explanation:

180 - (33 + 87) = 60

x = 60

180 - 60 = 120

y = 120º

or y = 33 + 87, because the outer angle of one angle equals the other two inner angles.

Answer: 120°

Step-by-step explanation:

If you add up all the triangles angles, it always is 180. So, when you add 33+87, you get 120. This means that x=60 because 120+60 =180.

Then, you also know that x and y together, make a 180° also because it is a straight line. So, y is equal to 120° because 60+120 = 180°.

Hope this helps! :)

Answer:

Step-by-step explanation:

1km = 1000m

5a. 5.768km = 5768m = 57.7m

5b. 9.039km = 9039m = 90.4m

5c. 8.48km = 8480m = 84.8m

5d. 17.685km = 17685m = 17.7m

5e. 17.658km = 17658m = 17.7m

To round to the nearest 100m just divide by 100 and then round it off. like 57.68=57.7m because 8 is more than 5 so 6 becomes 7 to one decimal.

Rule is applied for all the other questions too.

A line goes through the point (-8,9), and has a slope of 3/4

olya-2409 [2.1K]

Answer:

$y=\dfrac{3}{4}x+15$

Step-by-step explanation:

Given that,

A line goes through the point (-8,9), and has a slope of 3/4.

We need to express in the form of Ax+B for this line.

We have, m = 3/4

So,

$y=\dfrac{3}{4}x+B$

Put y = 9 and x = -8 in the above equation.

$9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15$

So,

$y=\dfrac{3}{4}x+15$

It is the required equation of the line.

Please help with an explanation

Vsevolod [243]

Answer:

the answer is incorrect though the first step is correct but the second step is wrong and so is the answer. the correct answer would be x raise to the power of 2by 5

Step-by-step explanation:

{x⁶/⁵⁻²/⁵} ¹/²= {x⁴/⁵}¹/²= x²/⁵

in the second step the power of the denominator must be subtracted from the power of the numerator using the law of indices then we would get the correct answer
