Step-by-step explanation:
angle ABC= angle ACB= 37° --------- because AB=AC
angle ACB+ angle ACD=180°
37+angle ACD=180
angle ACD=143°
Yes it's SAS
AD = CD (given)
BD = BD (common side )
but since it didn't say AC丄BD
it's no way to prove the angels r 90° :/
but as it already given AD= CD
so it's proven that it's an isosceles triangle
therefore
∠BAD = ∠BCD (base ∠s isos. ∆)
therefore it's SAS (side angel side)
0.5 inches ph * 3 hours = 1.5 inches
+ 10 inches he started with.
= 11.5 inches.
I don’t know about the second question
Answer:
1107.
You are rounding up because the number in the tenths slot is over 5.
They are equivalent because when you distribute the -0.5 into 3x+5 you get the expression -1.5x+2.5
