The problem is asking you to solve for the surface area of the triangular prism. You know that the prism is made up of two triangles and three square surfaces. Adding these surface together, will give you the surface area.
Solving for the surface area:
Surface area of 2 triangles (top and bottom) + Surface area of 3 rectangles (sides)
2 [1/2 (2.6)(3.9)] + [ (4.3)(3.9) + (4.3)(2.6) + (4.3)(5.2) ] = 60.45 cm^2 surface area

(a)When t=83
(b)When t=175
(b)When t=358
Answer:
XY = 11.25
Step-by-step explanation:
Corresponding sides of similar triangles are proportional.
XY/5 = 18/8
XY = 5(9/4) = 45/4
XY = 11.25
Answer:
m<0 = 50
Step-by-step explanation:
The opposite angles in an isosceles trapezoid are equal, so <T = <A
and <B = <O
We know the sum of all 4 angles has to be 360 since it is a quadrilateral
<T+<A + < B + <O = 360
Substituting what we know, and what we want to know
<T+ <T + <O <+O = 360
Combining like terms
2<T + 2 <0 = 360
2( 130) + 2<0 = 360
260 + 2< O = 360
Subtract 260 from each side
260-260 + 2< O = 360-260
2<O = 100
Divide by 2
2/2<O = 100/2
<0 = 50
