Step-by-step explanation:
m<ACB=m<CBD=90 degrees (given) and AB=DC (given)
BC=BC (reflexive property)
m<ABC=m<BCD (alternate interior angles)
triangle ABC is equivalent to triangle DCB by Angle Side Angle.
I think that's correct, I'm on this unit too.
Answer:
<B =121
Step-by-step explanation:
If the angles form a linear pair, they add to 180
6x-19 + 11x-22 = 180
Combine like terms
17x -41 = 180
Add 41 to each side
17x-41+41 = 180+41
17x = 221
Divide by 17
17x/17 =221/17
x =13
<b = 11x-22 = 11*13 -22 = 143-22 =121
Answer:
192
Step-by-step explanation:
16 times 12 is equal to 192
6+5+2=13. There are 13 tennis balls in each bag. There are 3 bags. 13x3=39. Martina has 39 tennis balls in all.
