Answer:
1.) x = 50 2.) x = 70
Step-by-step explanation:
These angles are complementary angles meaning the angles add up to 90°. Therefore, we can set up equations to solve for the variables.
1.)
x + 40 = 90
x = 50
2.)
x + 20 = 90
x = 70
Answer:
12cos59, about 6.18
Step-by-step explanation:
cos59 = x/12
(adjacent/hypotenuse)
x = 12cos59
plugging this into a calculator gets you about 6.18
Answer:
B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2).
Step-by-step explanation:
Samuel should is looking to find the area of his basement in order to cover it with carpet.
An area is calculated by multiplying two dimensions (so answers A and D are not it).
Best solution is to divide the area into two large rectangles then ADD them together to get the total area.
The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m). He would have achieved the same result of course, but by going a different way.
Answer:
The circumference of the clock is 
Step-by-step explanation:
we know that
The circumference of a circle (clock) is equal to
In this problem
The long of the minute hand is the radius of the circle
so
substitute
-----> exact value of the circumference
The equation is y = mx + b
(18, -19)
substitute these numbers in the equation
-19 = 0(18) + b
-19 is y because it is the y slot in the cordinate and I put 0 for m because m is the slope and x is 18
-19 = 0 + b
b= -19
the equation is
y = 0(x) - 19
y = -19
