Answer:
27 in
Step-by-step explanation:
The relationship between angle A, adjacent side AC, and hypotenuse AB is ...
Cos = Adjacent/Hypotenuse
cos(A) = AC/AB
Multiplying by AB, we get ...
AC = AB·cos(A)
AC = (30 in)cos(25°)
AC ≈ 27 in
Answer:
The ordered pairs for 1 and 3 are:
(1,2) (3,8)
Now use the slope formula:
(y2-y1)/(x2-x1)
(8-2)/(3-1)= 6/2 = 3
Step-by-step explanation:
Answer:
f(g(x))=9-x-
Step-by-step explanation:
Given ,
f(x)=9-x
g(x)= +x
here,.
fog
=f(g(x))
=f( +x)
=9-( +x)
=9- -x
=9-x-
Answer:
See below
Step-by-step explanation:
11 = 12 = 15 = 16 = 51 each vertical angles are congruent
10 + 11 = STRAIGHT LINE = 180 so 10 = 129 degrees
10 = 13=14 = 17 = 129 degrees each vertical angles are congruent
