You are going to use the cos trig function as you have the adjacent side and the hypotenuse.
Cos^-1(12/13)=angle x

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
Both of the other angles are 40° because a triangle has a total angle of 180° and an isosceles triangle means that at least two of the sides have to be the same length (two angles must be the same)
180 - 100= 80
80 ÷ 2 = 40
Answer:
A or the first answer is correct
Step-by-step explanation:
3650 - 2000 = 1650
1650 / (divided by) 150 = 11
you can also check your work by doing 150 *(times) 11 = 1650
1650 + 2000 = 3650
