Answer:

(2x+14)+(x+7)=90

Step-by-step explanation:

Remember that a line has an angle measure of 180 degrees and a right angle measures 90. Since EBD is a right angle, you know that (2x+14)+(x+7) has to equal 90 degrees in order for the EBA to be 180 degrees.

Answer: (2x+14) + (x+7) = 90

Step-by-step explanation:

Since the angles DBC and CBA share a common vertex of B and are perpendicular to the 90-degree angle beside them, they are complementary angles, meaning that the sum of their angle measures is 90 degrees. Knowing this, you can set up the equation (2x+14) + (x+7) = 90 in order to find the value of x.

I hope this helps!
