Answer:
Step-by-step explanation:
The angles marked with x-expressions are complementary, so ...
(3/4x -2) + (2/5x) = 90
x(3/4+2/5) = 92 . . . . . . . add 2
x(23/20) = 92 . . . . . . . . combine the fractions
x = 92(20/23) . . . . . . . . multiply by 20/23
x = 80
__
The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...
y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32
y = 122
Answer:
d=6in
r=3in
h=8in
drag those number in the formula.
SA=2(3.14)(3)^2+2(3.14)(3)(8)
SA=56.52+150.72
SA=207.24
The answer is:
207.24 squre inches
I believe it is x=6 because 13-7=6
Answer:
A
Step-by-step explanation:
the x value is 2 and if you count up u count six there for gives you (2,6)
