Answer:
4,500
Step-by-step explanation:
150 x 30
15 x 3 = 45, add 2 0's at end, 4,500
15 is a positive value, -3 is a negative value.
A positive value is always greater than a negative value.
The answer is: 15 > -3
2x - 4 = 8
2x = 8 + 4
2x = 12
x = 6
so he answer is e. 6
We know that
the law of sinus established
a/sin A=b/sin B=c/sin C
so
A=30°
B=45°
b=10 units
a/sin A=b/sin B---------> a/sin 30=10/sin 45------> a=10*sin 30/sin 45
a=7.07 units
C=180-(A+B)-------> C=180-(75°)-----> C=105°
b/sin B=c/sin C--------> c=b*sin C/sin B----> c=10*sin 105/sin 45
c=13.66 units
Area=(1/2)*b*c*sin A-------> Area=(1/2)*10*13.66*sin 30°-----> 34.15 units ²
the area of triangle is 34 units²
Answer:
im not fully sure but I'd say it is 9(5+0.78)
