Answer:
90.5 degrees
Step-by-step explanation:
The sum of the angle in triangle XYZ is 180 degrees, hence;
m<XYZ + m<YXZ + <XZY = 180
Substitute the given angles
75 + 14.5 + <XZY = 180
89.5+m<XZY = 180
m<XZY = 180 - 89.5
m<XZY = 90.5 degrees
Hence the measure of angle XZY in degrees is 90.5 degrees
The answer is 75 as you would divide 45 by 0.6
Answer:

Step-by-step explanation:
Given equation: 
The roots of the given quadratic equation are the values of x when
.
To find the roots, use the quadratic formula:

Therefore:




Therefore:

Answer:
x =39°
the total interior angles of a triangle is 180°
let the unknown angle be x,
solve:
x + 39 + 102 = 180°
x = 180° - 39° - 102°
x = 39°
Therefore the unknown angle is 39°
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
