3. If m∠EBF = 6x + 4 and m∠CBF = 7x - 2, find m∠EBF. 4. If m∠3 = 4x + 10 and m∠4 = 5x, find m∠4. 5. If m∠3 = 6y + 2 and m∠4 = 8y - 14, find m∠CBE. 6. Let m∠1 = m∠2. If m∠ABE = 100 and m∠ABD = 2(r + 5), find r and m∠DBE.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
