Answer:
70
Step-by-step explanation:
The angle not marked in the top triangle is 40 degrees since it is an isosceles triangle. That makes the angle opposite it in the other triangle 40 degrees since they are vertical angles and vertical angles are equal.
The bottom triangle has 3 angles that sum to 180 degrees, The other angle not marked is also y since it is an isosceles triangle.
40 + y +y = 180
Subtract 40 from each side and combine like terms
40-40 +2y = 180-40
2y = 140
Divide by 2
2y/2 = 140/2
y = 70

Given
Model to Actual = 5:9
5cm in Model = 9cm actual
1cm in model = (9/5)cm = 1.8cm
36cm in model = 1.8cm x 36 = 64.8cm
Answer:
m = variables
+4 = Coefficients
-7 = Coefficients
and 2 and 6 are Constants
