Answer:
32 minutes
Step-by-step explanation:
80% = .80
40 * .80 = 32
Answer:

Step-by-step explanation:
By the exterior angle theorem,

Group like terms and solve for x.


Divide both sides by 19;

Answer:
height ≈ 11.9 units
Step-by-step explanation:
Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.
Using the sine ratio in one of these right triangles, then
sin48° =
( the opposite is the height h )
sin48° =
( multiply both sides by 16 )
16 × sin48° = h , thus
h ≈ 11.9 ( to the nearest tenth )
