Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
Answer:
70
Step-by-step explanation:
we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50
3 angles in the equilateral triangle are equal to 60
we have 50 + 60 +h =the angle of PQR =180
h=70
A- 1gb=3$ 30$+(3*gb used)= total
B- 30$+(3*10)= 60$
Answer:
Step-by-step explanation:
There are two LEGS in a RIGHT TRIANGLE. In order to find the HYPOTENUSE, you must find the OPERATION. Then ROUND.
You divide 47,000 by 8. You should get 5,875. That should be the answer
