Complementary-angles that add up to 90 degrees
Supplementary-angles that add up to 180 degrees
Linear pair-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. (You could shorten that if you’d like)
Adjacent-Two angles that have a common side and a common vertex (corner point), and don't overlap
Congruent-angles that are equal
Parallel lines-side by side lines that will never touch

I don’t have time to finish the rest but I hope this helps

What’s the distance between (4,-9) and (5,3)

laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Given information

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

Given formula

$Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute values into the formula

$Distance = \sqrt{(5-4)^2+(3+9)^2}$

Simplify values in the parentheses

$Distance = \sqrt{(1)^2+(12)^2}$

Simplify exponents

$Distance = \sqrt{1+144}$

Simplify by addition

$Distance = \sqrt{145}$

Hope this helps!! :)

Need help will 11&12!

Zinaida [17]

Answer:

11.)60 degrees the lines on the triangle (the lil dashes) mean that that all the sides are equal making all the angles equal as well so all the angles equal 60 degrees.

12.) no, because in order for all the sides to be 12ft the angles have to be 60 degrees and this one is only 58 degrees so it wont exactly reach 12ft

Step-by-step explanation:

hope this helps :P

Samantha threw an apple out of a window from the tenth floor of her apartment building.The equation y=-16t^2+120 can be used to

Savatey [412]

If the apple is on the ground, then the height y is 0. To find t, just plug in 0 for y:
$0=-16t^{2}+120$
$-120=-16t^{2}$
$t^{2} =7.5$
$t=2.74$

So the answer is 2.74 seconds.

Note that taking the square root of 7.5, mathematically, gives you both 2.74 and -2.74. But because we know that time did not go backwards, only the positive value for t was considered.

Solve the equation 2/3 h - 1/3 h + 11 = 8 h = ?

Deffense [45]

Answer:

$2 \div 3h - 1 \div 3 h+ 11 = 8 \\ 2 - 1 \div 3h = - 3 \\ 1 \div 3h = - 3 \\ - 9h = 1 \\ h = - 1 \div 9$

-1/9 is the answer
