No because 7/9= 0.777777777789 and 8/9= 0.888888888888889
Answer:
B
Step-by-step explanation:
You first must find the conversion rate. Since you know a 4 ft tall object produces a 5 foot long shadow, you simply divide 4 by 5. This gives you 0.8. Now that you have your conversion rate, you multiply it by the shadow the tree casts, that being 125, and your answer is B, 100.
The slope is given by (y2 -y1)/(x2 -x1) = (11 -5)/(-2 -0) = 6/-2 = -3.
The point-slope form of the equation of a line with slope m through point (h, k) is
y - k = m(x - h)
For m = -3, and (h, k) = (0, 5) the equation is
y - 5 = -3(x - 0)
Answer:
m<ABD==65°
Step-by-step explanation:
we know that
1) The triangle DFB is an isosceles triangle, because
DF=BF=radius of the circle
2) BF is perpendicular to the tangent AC at point B
3) The measure of angle m<ABF=90°
4) The measure of angle m<DFB is equal to the measure of arc BD by central angle
so
m<DFB=130°
5) The measure of angle m<DBF=(180°-m<DFB)/2
so
m<DBF=(180°-130°)/2=25°
6) m<DBF+m<ABD=m<ABF
m<DBF+m<ABD=90°------> complementary angles
25°+m<ABD=90°
m<ABD=90°-25°=65°
