Answer:
HL (Hypotenuse Leg)
Step-by-step explanation:
You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.
First do 6×8=48, then just add the 0's to the end to get 480,000
Answer:
48
Step-by-step explanation:
Cat = x
Dog = 8x
x + 8x = 54
9x = 54
x = 6, Dog = 8 * 6 = 48
Answer:
x = (74-28)/2
Step-by-step explanation:
We find the perimeter of a triangle by adding the sides together
s1 +s2+s3 = P
The perimeter is 74
s1 +s2+s3 = 74
We know one of the sides is 28
28 +s2+s3 = 74
The other two sides are equal in length, call them x
28 +x+x = 74
Combine like terms
28+2x = 74
We want to solve for x
Subtract 28 from each side
28-28+2x = 74-28
2x = 74-28
Divide each side by 2
2x/2 = (74-28)/2
x = (74-28)/2
