Step-by-step explanation:

The exterior angle is the sum of the opposite interior angles of the triangle.

Therefore, m<D +m<C = 118°

=> 8y+3 +3y+5 = 118°

=> 11y = 118° - 8°

=> 11 y = 110°

=> y = 10°

m<D = 8y+3

= 8(10)+3 = 83°

m<C= 3(10)+5 = 35°

m<DEC = 180° -118° = 62°

The system of linear inequalities x + 10y ≤ 80, x ≥ 30 and y ≤ 4 is represented in a graph below

<h3>Graph of Linear Inequality</h3>

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

To solve this problem, we would require the use of graph which can easily be done with a graphing calculator.

x + 10y ≤ 80

x ≥ 30

y ≤ 4

The graph of the inequalities is attached below

Answer:

CA = 32

Step-by-step explanation:

By intersecting chords theorem:

12(4x + 1) = 14(3 + 3x) \\  \\ 48x + 12 = 42 + 42x \\  \\ 48x - 42x = 42 - 12 \\  \\ 6x = 30 \\  \\ x =  \frac{30}{6}  \\  \\ x = 5

CA = 14 + ( 3 + 3x)

CA = 14 + ( 3 + 3*5)

CA = 14 + ( 3 + 15)

CA = 14 + 18

CA = 32

How to solve 3(2x-7)=5x+4
notka56 [123]
You have to start by using the distributive property on the left side.
3(2x-7)=5x+4
6x-21=5x+4    Then remove and combine alike terms.
    +21      +21
6x=5x+25
-5x  -5x
x=25
