Answer:
your answer is -19.1
Step-by-step explanation:
you add -3.6 and -15.5 to get -19.1
to determine that 15.5 is negative look at key words surrounding it, like decreased, that tells you that your number is a negative.

Step-by-step explanation:
The missing measures can be found by making use of the properties of tangents, special triangles, trig functions, and circles.
RadiiAll of the incircle radii are the same length:
CJ = CK = CL = 4
AnglesAll of the segments to the incenter from the triangle vertices are angle bisectors. Of course, the sum of angles in a triangle is 180°, and the acute angles in a right triangle are complementary.
∠CML = ∠CMJ = 20°
∠CPL = ∠CPK = 40° . . . . . (∠P = 180° -40° -60° = 80°)
∠CNJ = ∠CNK = 30°
The central angles are complementary:
∠MCL = ∠MCJ = 70°
∠PCK = ∠PCL = 50°
∠NCJ = ∠NCK = 60°
TangentsThe two tangents from a vertex are congruent. Each will be the radius divided by the tangent of the (half) vertex angle.
ML = MJ = 4/tan(20°) = 11.0
PL = PK = 4/tan(40°) = 4.8
NJ = NK = 4/tan(30°) = 6.9
Angle bisectorsThe length from each vertex to the incenter will be the radius divided by the sine of the (half) vertex angle.
MC = 4/sin(20°) = 11.7
PC = 4/sin(40°) = 6.2
NC = 4/sin(30°) = 8.0

Additional comment
The given dimensions are slightly off. The angle at M is 19.9831°, or the length LM is 10.9899 units, or the radius is 4.00367. In order to keep the numbers nearly consistent, we have rounded to one decimal place. The 30° triangle is the only one with an angle that has a rational trig function (sine).
In a triple batch of spice mix, there are 15 teaspoons of salt and 6 teaspoons of garlic powder. how much salt is used with 8 teaspoons of garlic powder?
in a triple batch of spice mix, there are 15 teaspoons of salt and 6 teaspoons of garlic powder. how much salt is used with 8 teaspoons of garlic powder?
Answer:
2 teaspoons
Divide 15 by 5:
15/5 = 3
Divide 6 by 3:
6/3 = 2
Thus, there are 2 teaspoons of garlic powder used :)

It takes Tyreke 28 minutes to bike to his school, which is 7 miles away
If Tyreke continues to pedal at this pace, how long would it take for him to get to the soccer field, which is 8.8 miles away from school?
Answer:
35.2 minutes
Step-by-step explanation:
Time taken=28min
Distance=7miles
Speed=7/28=0.25milesperminute
Time=distance/speed
Time=8.8/0.25
=35.2 minutes
