Answer:
46.95 in.²
Step-by-step explanation:
Surface area of the kaleidoscope = surface area of a triangular prism = 2(BA) + P*H
Base area (B) = 2(½*bh) = 2(½*1.5*1.3) = 1.95 in.²
Perimeter of base (P) = 1.5 + 1.5 + 1.5 = 4.5 in.
Height of prism (H) = 10 in.
Plug in the values
Surface area = 1.95 + 4.5*10 = 46.95 in.²
Answer:
x = 5/7 -> 0.714285 which to the nearest tenth would be 0.7
Step-by-step explanation:
is it x*2 or x^2?
If it were x to the power of two, then the answer would be about x1 = 0.594875 and x2 = 8.40512
Answer:
8
Step-by-step explanation:
Step-by-step explanation:
sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
Answer:
Angle DGF = DEF
Step-by-step explanation:
Since all the angles are congruent in the diagram and the hypothenuses are both congruent, it makes the other triangle, DEF congruent to DGF.
In other words, sense all 3 angles are congruent and they share a side, DEF is congruent to DGF.
