15)
an exterior angle equals the sum of the remote interior angles
<span>so
m<XYT = m<X + m<Z
4x - 25 = x + 15 + 50 - 3x
4x - 25 = -2x + 65
6x = 90
x = 15
answer
x = 15

Write the parent function in the standard form I.e.

Where,




10. 4y + 2
11. 7x
i will put the other two in a bit something happened to my thing that it only lets me write some things
Answer:
9
Step-by-step explanation:
As x gets large, the only terms of interest are the ones of highest degree.

Answer:
x = 50°
Step-by-step explanation:
Recall that for a triangle, the exterior angle is equal to the sum of its two remove interior angles (also see attached for reference).
in our case, the exterior angle is given as 105° and its two remote interior angles are x and 55°
therefore
105° = 55° + x
x = 105° - 55°
x = 50°
