How do you find the angles on this special triangle?

Mathematics

Well this is simple. First you have to know what type of formula your gonna be using. Which means you can’t use a squared+b squared=c squared.
So first you look for what angles you do have and that’s a 90 degree angle. Next you look for other givens like the two side are even. Now you know it’s a Isosceles triangle. So since we know we have 90 degree angel already and there can only be 90 left becasue it’s only 180 degrees in a triangle and 90+90 makes 180. You divid 90 by 2 and it gives you 45 and that’s the other two angles. Anther name for the triangle is 45,45,90 it’s called for special triangles when using square root.

Answer:

it is isosceles triangle with an angle = 90. Two others angle are equal. sum of all angles in triangle is 180.

2x + 90=180 --> x=45

Which operation is going to be performed first <br>3÷2+(10-2×4)​
sergejj [24]

Answer:

parenthesis

Step-by-step explanation:

Hello!

To know what the order of operations is we go by PEMDAS

Parenthesis then Exponents then multiplication and division from left to right then addtion and subtraction from left to right.

Since parenthesis are in this equation we would do those first

The answer is parenthesis

Hope this helps!

The inverse, converse and contrapositive of a statement are used to determine the true values of the statement

<h3>How to determine the inverse, converse and contrapositive</h3>

As a general rule, we have:

If a conditional statement is: If p , then q .

Then:

  • Inverse -> If not p , then not q .
  • Converse -> If q , then p .
  • Contrapositive -> If not q , then not p .

Using the above rule, we have:

<u>Statement 1</u>

  • Inverse: If a parallelogram does not have a right angle, then it is not a rectangle.
  • Converse: If a parallelogram is a rectangle, then it has a right angle.
  • Contrapositive: If a parallelogram is a not rectangle, then it does not have a right angle.

All three statements above are true

<u>Statement 2</u>

  • Inverse: If two angles of one triangle are not congruent to two angles of another, then the third angles are not congruent.
  • Converse: If the third angles of two triangle are congruent, then the two angles are congruent to two angles of another
  • Contrapositive: If the third angles of two triangle are not congruent, then the two angles are not congruent to two angles of another

All three statements above are also true

The line segment formed by joining points A (-1,y) B (0,0), and the line segment joined by forming points C (6,3) D (8,9) share
Airida [17]

Answer:

<h3>-3</h3>

Step-by-step explanation:

For two parallel lines. their slope are equal

Find the slope of each of the lines

For line A;

m = 0 -y/0+1

mA = -y/1

For line B;

mB = 9 - 3/8 - 6

mB = 6/2

mB = 3

since their slope are equal hence mA = mB

-y/1 = 3

-y = 3

y = -3

Hence the value of y is -3
