Answer:
measure angle D = 62
Step-by-step explanation:
as the sum of measures of triangle =180
then (8x-40)+(4x-10)+(3x+20)=180
15x-30=180
x=(180+30)/15=14

Answer: A Single Solution
Step-by-step explanation:
The set when z = -5 is {-27, -9, -5}
<h3>How to determine the set elements?</h3>
The set is given as:
{(4z-7,z-4,z) |z is any real number}
When z=-5, we have:
4z - 7 = 4(-5) - 7 = -27
z - 4 = -5 - 4 = -9
z = -5
So, we have:
{(4z-7,z-4,z) |z is any real number} ⇒ {-27, -9, -5}
Hence, the set when z = -5 is {-27, -9, -5}
