2.5
Step-by-step explanation:
4x2.5=10
Answer:
130⁰. unsure. angle sum, 25+25+x =180, so x=180-25-25
Answer:
(D) 2
Step-by-step explanation:
The scale factor of the enlargement of ΔABC to ΔA'B'C' is given by the ratio of the length of the corresponding sides of ΔA'B'C' and ΔABC
Therefore, we have;
Therefore, the scale factor = 2
Given:
To find:
The length of QR.
Solution:
We have,
Then, (CPCTC)
Divide both sides by 4.
Similarity,
(CPCTC)
Divide both sides by 2.
Now,
Therefore, the correct option is d.
7(x+2)= 7x + 14
7x + 14 = 7x + 14
