Answer:
The answer is A.
Step-by-step explanation:
64 is a cube number of 4.
4 × 4 × 4 = 64
Answer:
x = 5.85
Step-by-step explanation:
Given that,
One angle = 26°
Middle angle = 90°
Third angle = 180-(90+26) = 64°
Height, H = 12
We need to find the value of x. Using trigonometry to find it such that,
![\tan64=\dfrac{12}{x}\\\\x=\dfrac{12}{\tan(64)}\\\\x=5.85](https://tex.z-dn.net/?f=%5Ctan64%3D%5Cdfrac%7B12%7D%7Bx%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B12%7D%7B%5Ctan%2864%29%7D%5C%5C%5C%5Cx%3D5.85)
So, the value of x is equal to 5.85.
X is 4 more than 5 times y
x=4+5y
if sum is increased by 3 (x+y+3), result is 31
x+y+3=31
minus 3 both sides
x+y=28
x=4+5y subsiutute
4+5y+y=28
4+6y=28
minus 4 both sides
6y=24
divide by 6
y=4
sub back
x=4+5y
x=4+5(4)
x=4+20
x=24
the numbers are 24 and 4
