Solve for X geometry

Answers

1. x=7

2. x=6

3. x=9

4. x=8

Explanations

1. This is an isosceles triangle because two angles are congruent. This also means the two sides are the same. This means  7 = x.

2. This is an equilateral triangle because all the angles are the same. Therefore, all sides are also the same. So x = 6.

3. This is also an equilateral triangle. We know this because all sides are the same. So from this we know that x-3 = 6. Solve the equation, and you'll find that x = 3.

4. This is also an isosceles triangle, because two of the angles are congruent. This means 2x-9 = 7. Solve this equation; x=8

27) x = 7

28) x = 6

29) x = 9

30) x = 7

Step-by-step explanation:

I first added to two angles we already knew. Then, I took that number and subtracted it from the whole number in the algebraic equation. I then divided that number with the value paired with x to get x.

Sorry, it is hard to explain with words. Please give the person above me a reward. They answered before me.

I hope this helps you!

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
