I know it equals 180 I’m just confused.
1 answer:
A whole triangle is total of 180°
as the two angles are same which is x, hence it is an isosceles triangle.
so using all the angles given,
46° + x° + x° = 180
by collecting all the like terms,
46° + 2x° = 180
GET RID of 46° on the left hand side
ADD of 46° on the right hand side
2x° = 180° - 46°
2x = 134°
now divide all with 2
2x÷2 = 134÷2
x° = 67°
therefore, the answer is x = 67°
as the two angles are same which is x, hence it is an isosceles triangle.
so using all the angles given,
46° + x° + x° = 180
by collecting all the like terms,
46° + 2x° = 180
GET RID of 46° on the left hand side
ADD of 46° on the right hand side
2x° = 180° - 46°
2x = 134°
now divide all with 2
2x÷2 = 134÷2
x° = 67°
therefore, the answer is x = 67°

<h2><em><u>Answer:</u></em></h2>
Total Surface Area = 375
You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls
<u>Area of the ceiling:</u>
c = length * width
c = 9*6.5 = 58.5
<u>Area of the 2 rectangle walls:</u>
w = 2(length * width)
w = 2(9 * 8)
w = 2(72)
w = 144
<u>Area of floor:</u>
f = 9 * 7.5
f = 67.5
<u>Area of the two trapezoids:</u>
a = 6.5
b = 7.5
h = 7.5
Total Surface Area = c + w + f + t
Total Surface Area = 58.5 + 144 + 67.5 + 105
Total Surface Area = 375
