Answer:
20 degrees
Step-by-step explanation:
If ZWV = 115 then ZYX = 115.
115 + 45 = 160, 180 - 160 = 20
Answer:
yes it is a rational number
Step-by-step explanation:
Answer:
Area of wall = length × breadth
Here, length = 80 m and breadth = 15 m.
= 80 × 15 sq. m.
= 1200 sq. m.
Therefore, painting the wall = area × cost per square unit.
Given, rate = $ 4 per sq. m.
= 1200 × 4
= $ 4800.
In problem 16 I think the answers is b
The distance between the points (x₁,y₁) and (x₂,y₂) is calculated through the equation,
d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
From our given, we have the point (-3,-1) and (1,y). Substituting these to the equation,
5 = sqrt ((-3 - 1)² + (-1 - y)²)
Squaring both sides,
25 = (-3 - 1)² + (-1 - y)²
The values of y from the equation are 2 and -4.
The answers are therefore: (a) <em />(<em>1, 2)</em> and (b) <em>(1, -4)</em>.
