4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
Answer:
x=42 degrees
y= 66 degrees
z=66 degrees
Step-by-step explanation:
X is equal to 42 degrees because all angles in a triangle add up to 180, and since we are given two angles of the triangle, we can add them, then subtract the answer from 180.
48+90=138
180-138=42
Therefore x is 42 degrees.
For angle y and z, they are made up of 3 angles that equal 180. We have one angle measurement given, 48. So we would subtract that from 180, then divide the answer by 2.
180-48=132
132/2=66.
Therefore y and z is 66 degrees.
