Answer: The Awnser to this equation is C, AE is equal to 25
Answer:
see explanation
Step-by-step explanation:
1
(x + 5)² = 4 ( take the square root of both sides )
x + 5 = ± = ± 2 ( subtract 5 from both sides )
x = - 5 ± 2, thus
x = - 5 - 2 = - 7
x = - 5 + 2 = - 3
--------------------------------------------
2
(x + 6)² = 7 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± , thus
x = - 6 -
x = - 6 +
------------------------------------------------
3
(x - 2)² = 18 ( take the square root of both sides )
x - 2 = ± = ± = ± 3 ( add 2 to both sides )
x = 2 ± 3, thus
x = 2 - 3
x = 2 + 3
Answer:
1/cos^2(180-theta) - 1
Step-by-step explanation:
According to trigonometry identity
tan^2 theta + 1 = sec^2 theta
tan^2 theta = sec^2 theta - 1
hence tan^2(180-tetha) = sec^2 (180 -theta) - 1
tan^2(180-tetha) = 1/cos^2(180-theta) - 1
Hence the value of tan^2(180-tetha) is 1/cos^2(180-theta) - 1
Answer:
r=16
Step-by-step explanation:
2r = 37-5
2r = 32
r = 16
The picture in the attached figure
the question is
What is the surface area of the ramp?
we know that
surface area=2*[(36+12)*5/2]+2*[15*13]+[12*15]+[36*15]
surface area=240+390+180+540
surface area=1350 in²
the answer is1350 in²
