The answer to your equation is z = 7
I’m not sure if the 15 is the question number but if it is the answer is 32. use PEMDAS
The answer is 7 because 70 ÷ 10 = 7.
Question:
The image of the question is attached below.
Answer:
x = 40
Solution:
Given ΔVDG
ΔVNG.
DG = 207, NQ = 138, GQ = 60, QV = x
In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.


Do cross multiplication, we get



Divide by 207 on both sides of the equation, we get


⇒ x = 40
⇒ QV = 40
Hence the value of x is 40.
