135

Step-by-step explanation:

Supplementary means both angles equal 180 degrees when combined

180 - 45 = 135

Complementary means both equal 9 degrees when combined

if u think connect the lines of S and it makes and 8 for 180 and C makes 9 for 90

Uca is designing a propeller system that consists of 3 blades, each of which is

zmey [24]

Answer:

The weight of the three blades together is $134\ g$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=4\ in$

assume

$\pi=3.14$

substitute

$A=(3.14)(4)^{2}$

$A=50.24\ in^{2}$

step 2

Find the area of the 3 blades

we know that

The area of the 3 blades represent a central angle of 60 degrees, so

its a 1/6 of the area of complete circle

$A=50.24/6=8.37\ in^{2}$

step 3

Find the weight of the three blades together to the nearest gram

$(8.37\ in^{2})*(16\ g/in^{2})=134\ g$
