In geometry, if 2 angles are congruent, then their corresponding sides are also congruent. So you can have 3x-5=2x+9 & solve for x. Then substitute that value into all the other expressions to get the measures of all 3 sides. From there, you can determine the type of triangle
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
