Determine the measure of each angle
The angles in a triangle sum up t 180. i.e.
Since , then
can then be rewritten as:
Substitute values for B and C
Open Bracket
Collect Like Terms
Divide both sides by 23
To get the measure of each angle, substitute 11 for x in the expressions of B, C and D
Answer:
I got B) 72 cm^3
Step-by-step explanation:
cube area= 4
rectangle area= 18
4*18= 72
Remember
note that if
is a perfect cube then
is also a perfect cube when c is an integer
so if a number is a perfect cube then the power must be divisible by 3
8 is not divisible by 3
24 is divisible by 3
26 is not divisibley by 3
64 is not divisible by 3
the perfect cube is y^24
A) How high up the wall does it reach?
Use the Pythagorean theorem
Height^2 + Base^2 = Hyp^2
H^2+ 2^2 = 4^2 Subtract the 2^2 from both sides
H^2 = 4^2 -2^2 Multiply the square roots of both the numbers
H^2= 16 - 4
H^2 = 12
H= sqrt(12) m
