We know that
<span>the rotation of a solid does not modify the values of the internal angles of the solid
</span>therefore
interior angle after 90° rotation=interior angle before 90° rotation
interior angle after 90° rotation=108°
the answer is the option D 108 °
9 the smallest angle is always opposite the smallest side
Answer: choice d, angle B
They couldn't match the choice letters with the angles? Geez.
10. That's an isoscles triangle
d + d + 116 = 180
2d = 64
d=32
choice a
11. 62+45+k=180
k=180-107 = 73
choice b
Answer:
C) (0,5)
Step-by-step explanation:
f(x) is y and x is x
The table is providing you with points
y-y over x-x gives you a slope of -5
Use the points and turn it into a point-slope equation and convert to y-intercept equation
y-15=-5(x+2)
y-15=-5x-10
y=-5x+5
So the y-intercept is 5 or (0,5)
