The measure of ∠dab equals 125º. the measure of ∠acb equals 30º. what is m∠abc? enter your answer in the box. triangle a b c with ray a d extended from side a c.

Firstly, we will draw diagram of this problem

we are given

∠DAB=125º

∠ACB=30º

Since, ∠DAB is exterior angle

∠ACB   and ∠ABC  are interior angles

and we know that

exterior angle is sum of two interior angles

so, we get

∠DAB=∠ACB +∠ABC

now, we can plug values

125º=30º+∠ABC

∠ABC=95º.............Answer

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
