55 times 3 is 165
12 + x= 12x
Your answer would be B.
Answer:
(see below)
Step-by-step explanation:
First, to make it easier for yourself, "flip" the triangles so that they "match." To see what I'm talking about, refer to IMAGE.A.
Now that you can tell that the congruent side and angles are corresponding, you have to prove them congruent.
There is one side and two angles, so it's AAS or SAA.
Answer:
62.1467 square units (correct to four decimal places)
Step-by-step explanation:
Let's say the triangle is;
A(-7,5)
B(-4,1)
C(0,1)
Let's say also that AB = a , BC = b and AC = c
By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.
Area of this triangle =
, where p is half the perimeter of the triangle
p =
units
Area =
= 62.1467 square units (correct to four decimal places)
Answer:
40,000
Step-by-step explanation:
refer to attached.
the number 4 is found in the Ten Thousands (10,000) place
hence the number 4 has the value of
4 x 10,000
= 40,000
