Let
<span>p ----------------> is the perimeter of the base
</span><span>h ---------------> is the height
</span><span>BA-------------> is the area of the bases
</span><span>LA--------------> is the lateral area
we know that surface area is </span><span>the sum of base areas plus lateral areas
</span><span>then
SA=[BA]+P*h
but remember that
LA=P*h
then
SA=</span>[BA]+LA----------> SA=BA+LA
the answer are the options B.) SA=BA+LA and the option D.) SA=BA+ph

Answer:
m∠1 = 71°
Step-by-step explanation:
Angle 1 and 2 are complementary, meaning the measures of the two angles add up to 90°.
Set the measures of the two angles equal to 90°

Combine like terms

Solve for x

Plug the value of 'x' back into the given equation for the measure of angle 1

m∠1 = 71°
Answer:
48
Step-by-step explanation:
The square pyramid has exactly the same four triangles.
In order to find the whole surface area, we must find the area of one of the triangles and multiply them by 4.
Surface area of square pyramid = 
Where we know that b = 4 and h = 6.
Substituting into the formula should give us the answer 48.
