In ΔLMN, m∠L = 108°, m∠M = 25°, and ℓ = 12. What is m?
Alex_Xolod [135]

Answer:

m = 5.33

Step-by-step explanation:

First we need to calculate angle N.

Sum of angles in a triangle is 180°

∠L + ∠M + ∠N = 180°

108°+25°+∠N = 180°

∠N = 180°-(108°+25°}

∠N = 180°-133°

∠N = 47°

Given side l = 12, to get m, we will use the sine rule.

l/sinL = m/sinM = n/sinN

12/sin108° = m/sin25°

m × sin108°= 12sin25°

m = 12sin25/sin108°

m = 5.071/0.951

m = 5.33

I need help on number 23
babunello [35]
Angle a,b,c equals 222; because angle a and b already is 180; so there is a right angle in the top with a 48 degree next to it so add then up and its 138; now subtract 180 which is the total of the total angels with 138 and you get 42; now add that to 180 and you get your answer which is 222.

Dante is studying the growth of a particular type of plant. He is testing the effects of four growth factors: lighting, age, tem
Leya [2.2K]

The level from each growth factors is an illustration of combination

There are 90 ways of combining one level from each growth factors

<h3>How to determine the number of combination</h3>

From the complete question (see attachment), we have the number of levels in each growth factor is:

  • Lighting = 3
  • Age = 5
  • Temperature = 2
  • Humidity = 3

So, the number of combination (n) is:

n = 3 * 5 * 2 * 3

n = 90

Hence, there are 90 ways of combining one level from each growth factors
