Step-by-step explanation:
Given that
From the figure :
m angle 1 = 48°
Let m angle 2 = x°
And it is clearly m angle 1 and m angle 2 = 90°
90° = m angle 1 + m angle 2
Substitute the above values in equation then
⇛90° = 48°+x°
Shift the constant 50 from RHS to LHS, changing it's sign.
⇛ 90°-48° = x°
⇛42° = x°
⇛ x° = 42°
Therefore, m angle 2 = 42°
<u>Answer</u><u>:</u> Hence, the value of m angle 2 is 42°
<u>Additional</u><u> comment</u><u>:</u>
The sum of the two angles is 90° then they are Complementary angles. The Complementary angle of x° is (90-x)°

Answer:
x = 3
y = 2
Step-by-step explanation:
4x + 3(3x - 7) = 18 <em>Substitute</em><em> </em><em>y</em>
4x + 9x - 21 = 18 <em>Simply</em>
13x - 21 = 18 <em>Add</em><em> </em><em>like</em><em> </em><em>terms</em>
13x = 39 <em>Add</em><em> </em><em>2</em><em>1</em>
x = 3 <em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>3</em>
y = 3(3) - 7 <em>Substitute</em><em> </em><em>x</em>
y = 9 - 7 <em>Simply</em>
y = 2 <em>Subtract</em>
Let's check:
4(3) + 3(2) = 18
12 + 6 = 18
18 = 18
It works!
For AD to be parallel 2x+4º should be equal to 79º
2(37)+4 = 78º
78º<79º
Since they aren't equal the lines are not parallel to each other.
This is a linear programming question
if u want to solve the question, u can plot a graph(see the picture)
while x is n, y is r
and u may find out all of the integral values of x ,y in the required region, and sub them to 6450x+7150y=c, where c is the overall customers number, see which point give u the largest number of customers, u may get the ans then
