Can you me answer both questions for number 5 a.65 degrees b.115 degrees c.155 degrees d.171 degrees

4) The smallest angle is A) 40

5) The answer is C) 115

Step-by-step explanation:

5) CD bisects ACB

So ACD = DCB

3x-2 = 5x-20

3x-5x = -20+2

-2x = -18

x = 9

ACD = DCB = 25°

All angles in a triangle are equal to 180°

CD ⊥ AB

So CDB right triangle

∠DBC = ??

180-(90+25)

180-115 = 65°

∠CBF = 180°

∠DBF = 180-65 = C) 115°

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
