Answer:

Your answer is 30

we have 78 and 72 for the known sides so we have to input them in an addition like this

72^2 + x^2 = 78^2

we square them

5184 + x^2 = 6084

subract 5184 from the product

x^2 = 900

and then we find the square root of 900, the square root of 9 is 3 so the square root of 900 is 30

Find the measure of each angle.<br><br><br>If m∠EBC = 55° and m∠EBD = 20°, find m∠2
weeeeeb [17]

Using the angle addition theorem, the measure of angle 2 in the given diagram is: m∠2 = 35°

<h3>What is the Angle Addition Theorem?</h3>

Based on the angle addition theorem, the sum of two smaller angles that make up a bigger angle equals the sum of the bigger angle.

Given the following:

  • m∠EBC = 55°
  • m∠EBD = 20°

m∠EBC = m∠EBD + m∠2 [angle addition theorem]

Substitute

55 = 20 + m∠2

m∠2 = 55 - 20

m∠2 = 35°
