Hey You!
350 * 10% = 35
350 - 35 = 315
315 / 5 = 63
63 × 3 = 189
315 - 189 = 126
There are 126 red keys in the bin! =)
In order to calculate for the distance that Jose needs to
cover to go back to where he started, just use the concept of Pythagorean theorem.
First illustrate the given in triangular form. The missing side is the distance
covered by Jose. To calculate for the side just get the sum of the square of
the two number and then get the square root of the answer. The answer would be 5
km northwest.

Answer:
Step-by-step explanation:
<1+<2=90 complementary
<1=4 times <2
X+4x=90
5x=90
X=18
<1=18×4=72 degrees
<2=18 degrees
<1=<3 because they are vertical
Do <3= 72
<3+<4=180 because they are supplementary
72+<4=180
<4=108 degrees
<3=72 degrees
The longer leg is the leg adjacent to the larger angle
so 60
length of longer leg = 4 sin60 = 2sqrt(3)
