Question

Write and solve an equation that can be used to find x, in the figure below:

Answer 1

The correct answer is X=40 because

1. Add the 2 angles you already know.

30 + 63 = 93

2. The sum of all angles in a triangle is always 180°

180 - 93 = 87

3. third angle is 87°

2x + 7 = 87

4. Subtract BOTH sides by 7

2x = 80

5. Divide by 2

X = 40

Hope this helped!!!❤️

Answer 2

Answer: x=40

Explanation:

so you would add the two angles you already know.

30+63=93

The sum of the angles of a triangle is always 180°. Knowing this, you can do

180-93=87

so you know the third angle is 87°

plug this into the equation: 2x+7

2x+7=87

subtract both sides by 7

2x=80

divide by two

x=40
