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.

Is known that
(a + b)² = a² + 2.a.b + b²
So:
(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16
Answer:
the unknown number of fish is 26
Step-by-step explanation:
I figured this out by subtracting 68 - 47 = x.
x = 26
$18. You get this because you subtract 7 from 16 since that’s money he got. You get 9. Since Jack spent half his allowance money, you double the money he had left after spending it, giving you $18.
