Answer:
A. 2.82 m
Step-by-step explanation:
<u>The missing side we are trying to find is the hypotenuse, this is because it is the longest side of a right triangle.</u>
<em><u>The Pythagorean Theorem is used:</u></em>
<em><u /></em>
<em><u>Plug in the given numbers (2), accordingly:</u></em>
<em><u /></em>
<em><u>Take the square root of both sides:</u></em>
<em><u /></em>
2.82 ≈ c
Answer:
18
Step-by-step explanation:
area of the "left most" side disk would be
= 9
the height of the disk is = 2
thus the area would be 18
units cubed
Answer:
y = 1/5x + 2
Step-by-step explanation:
y = 1/5x + b
4 = 1/5(10) + b
4 = 2 + b
2 = b
X = (1/2)y + 6
x + y = 21
Substitute (1/2)y + 6 as x into the equation x + y = 21 since x = (1/2)y + 6.
[(1/2)y + 6] + y = 21
0.5y + 6 + y = 21
1.5y = 15
y = 10
Same thing, now substitute 10 as y in the other equation.
x + y = 21
x + (10) = 21
x = 11
Answer:
171.9 degrees.
Step-by-step explanation:
The factor is 180/π.
So 3 radians = (3*180)/π
= 171.9 degrees.
