Check the picture below.
segments AC and BC are equal, that means that ABC is an isosceles triangle, with twin sides. Now the twin sides make twin angles on the opposite side, namely the angles at A and B are twins.
if the angles at A and B are twins, and CD is ⟂ to AB, there's only one possibility that can happen, and is if CD is an angle bisector at C.
an angle bisector like CD with twin angles on each side, will cut AB in two equal halves, therefore, if AB = 4, then AD = 2 and DB = 2.
The answer is D
8x3x3 =72
5x3x9=135
72+135= 207 cm^3
Answer:
x = 87
Step-by-step explanation:
37 + 56 = 93
triangles always equal to 180
180 - 93 = 87
First of all, 25% of means that the new price was 75% of the original price, so:
25% off of $120.00
120.00×75%=$90.00
7.8% percent taxes
$90×7.8%=$7.02
Finally,
$90.00+$7.02=$97.02 is your final answer. Hope it help!
The answer is 4 square root 5 or -4 square root 5
