We are supposed to assume FC and AD is straight line
let's find all the angles
you already see the right angle is 90 degrees, you got that right
striaght line is 180 degrees
90+46+EF=180
136+EF=180
minus 136 both sides
EF=44
now we got another straight line
you did get that A F=46 because it is oposite
notice: AB=BC because same angle designition
so now we use
180+46+2AB=360
2AB=134
divide 2
AB=67=BC
AC=134 degrees
CAE=134+46+44=224
ABD=180 since straight line
a. 90
b. 224
c.134
d. 180
Answer:
9.55 in
Step-by-step explanation:
The formula for the circumference of a circle (or the circum. of a basketball) is C = πd, where d is the diameter.
Here C =30 in = πd, so
d = (30 in) / π
= 9.55 in, approx.
Answer:
y = - 3x + 10
Step-by-step explanation:
We have to write an equation of a straight line in slope-intercept form that passes through the points (3,1) and (0,10).
Now, the equation of the straight line (using two points form) will be
⇒ y - 1 = - 3(x - 3)
⇒ y - 1 = 9 - 3x
⇒ y = - 3x + 10 (Answer)
{Since the slope-intercept form of a straight line equation is y = mx + c}
We know the equation of a straight line when any two points on the straight line (
), (
) are known, will be
