Answer:
1. ΔCAT ≅ ΔODG by SSS, Angle D equals 45 degrees
Step-by-step explanation:
Triangles can be proven congruent or the same shape and size by 5 postulates:
- SAS - Side - Angle - Side
- ASA - Angle - Side - Angle
- AAS - Angle - Angle - Side
- SSS - Side - Side -Side
- HL - Hypotenuse - Leg
To state a triangle is congruent write ΔABC ≅ ΔDEF by ________ and name the pattern. Use the letters for each triangle you see to write or name it.
To identify the pattern, place your pencil on a vertex of the triangle. Trace it and label each congruent part as you come to it as S or A.
For number 1, this would be S - S - S or SSS
I think it’s d
I hope it’s true
Answer:
The value of x is 12
Step-by-step explanation:
4x3=12
7x3=21
Therefore 12/21
To explain further:
If you divide 12 by 3 you get 4
If you divide 21 by 3 you get 7
Therefore resulting to 4/7
(I found out that the number three goes in both numbers to begin with)
Is this clearer?
First you would start getting the denominators to the same number and you could do this by multiplying 9/10 by 4, and 7/8 by 5 to get the denominators to 40 and when you add the fractions you get 71/40 so the answer would be D. About 2
