Answer:
1. $2
2. $4
3. 2x
Step-by-step explanation:
(x+51)+(x+59)+84=180 (Sum of angles in a triangle)
2x= 180-194= -14
x=-7
Angle A: x+51=-7+51=44°
Answer:
352 m^2
Step-by-step explanation:
Each of the four congruent triangular faces has an area that is half the product of the base edge length and the slant height:
A = 1/2·bh = 1/2·(8 m)(22 m) = 88 m^2
Then the total lateral area is 4 times this:
LA = 4·88 m^2 = 352 m^2
