I need help finding the measure of the angles

Mathematics
1 answer:
sveticcg [70]2 years ago
4 0

Answer:

Every angle listed is 90 degrees

Step-by-step explanation:

First of all, we know that the angle with the red square is 90 degrees; that square is a symbol that represents right angles. If that angle is 90 that must mean that line t and line a are perpendicular. In a perpendicular intersection, 4 right angles are created. Additionally, since line b is parallel to line a; it must also be perpendicular with line t. Therefore, all of those angles are also 90 degrees.

The answer can also be found using the properties of 2 parallel lines and a transversal like corresponding angles and alternate side interior angles.

What’s the length of BD ?
Rina8888 [55]

Answer:

BD = 4.99

Step-by-step explanation:

You can simply use the trigonometric identity tangent to solve for length BD.

Tan = opposite/adjacent

In this case we have,

Tan 31 = 3/BD

BD = 3/Tan 31

BD = 4.99

The distance 2,4 7,2. Quasstion 2 is -6,-7. (0,0)
Kitty [74]
Please write your points by enclosing the x- and y-components inside parentheses:  (2, 4) and (7,2).  Use the distance formula.  Do you know it?

Distance between (2,4) and (7,2) is Sqrt ( [7-2]^2 + [2-4]^2 )

Note:  by "Quasstion" you most likely meant "question."

Which of these are a trinomial
Salsk061 [2.6K]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

D) c^2+c+6

»»————- ★ ————-««  

Here’s why:  

  • A trinomial is a expression that consists of three terms.
  • A term can be a number, variable, or both numbers and variables that are multiplied together.
  • Answer choice 'D' has three terms, c², 'c', and '6'. Therefore, it is a trinomial.

Hope this helps you. I apologize if it’s incorrect.
