B) 32°

Step-by-step explanation:

Triangle Exterior Angle Theorem: The TEAT states that the sum of the two interior angles is equal to the opposite exterior angle.

It is given that m∠DBC = 122°. Note that m∠C is a right angle, or 90°.

Subtract:

m∠DBC - m∠C = m∠A

Plug in the corresponding numbers to the corresponding variables:

(122) - (90) = m∠A

m∠A = 122 - 90

m∠A = 32

B) 32° is your answer.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
