Answer:
A = bh/2
39 = b*3/2
39*2 = b*3/2 * 2
78 = b*3
78/3 = b*3/3
26 = b.
Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi.
Answer:

Step-by-step explanation:
The right triangle has the hypotenuse = 18
Let 'Ф' be the missing angle
we know that
cos Ф = adjacent/hypotenuse
Here,
so
cos Ф = adjacent/hypotenuse



Therefore, the missing angle is:

Look at the slope in each equation. A neg. slope indicates that the function is decreasing. A pos. slope: increasing.

The numbers seem to be going up and down but definitely not by a pattern
Part a is 50 and part b is 20 at a 90 degree angle
