For this, we will be using Triangle Angle Sum Theorem (all interior angles in a triangle add up to 180°) for Triangle BCD. Since Angle CBD and BDC are congruent to each other and Angle BDA, we can solve for those two angles to get that angle. Our equation will look like this: 180=35+2x

Firstly, subtract 35 on both sides of the equation: 145=2x

Next, divide both sides by 2 and your answer will be 72.5 = x.

Since Angle CBD and BDC are 72.5°, this means that Angle BDA is 72.5° as well.

If < BCD IS 35 degrees
< ECD is exactly half of that 35/2= 17.5

< CED angle is 90 degrees

Because we know that in a triangle all angles combined add to 180 degrees that means that :

< EDC = 180 - 90 - 17,5 = 72,5 degrees

We know that the angle of < BDA is a mirrored angle of

Maya is trying to break or tie the league record for home runs in her softball league. She solved the inequality mc019-1.jpg to
Lelechka [254]
The correct answer would be letter C. She needs to either break or tie the record. The less than or equal to symbol in the original inequality would be her scoring less or tying the record. Using the greater than or equal to sign would represent her breaking the record or tying with it. Hope this helped.

∆ABC is reflected about the line y = -x to give ∆A'B'C' with vertices A'(-1, 1), B'(-2, -1), C(-1, 0). What are the vertices of
blsea [12.9K]
Hi there!
Reflections across the line y = -x always go by the rule (-y, -x). We can use this rule to get our answer here. We are given the aftermath of the reflection coordinates, which are <span>A'(-1, 1), B'(-2, -1), and C'(-1, 0). All we have to do now is switch up the coordinate values and multiply them by -1. Here is the work - 
A'(-1, 1) => (1, -1) => x -1 => A(-1, 1)
B'(-2, -1) => (-1, -2) => x -1 => B(1, 2)
C'(-1, 0) => (0, -1) => x -1 => C(0, 1)
Therefore, the coordinates of Triangle ABC are A(-1, 1); B(1, 2); C(0,1). Hope this helped and have a phenomenal day!</span>
