Answer:
x = 23
Step-by-step explanation:
60°=x+14
60+14=84=X
Answer:
9.5
Step-by-step explanation:
(0.5^2 + 0.5^-2 + 0.5) / 0.5 = 9.5
Hope this help! :)
Answer:156
Step-by-step explanation:
Imagine for a group of 15 (8 boys and 7 girls), you will have 8 girls. So the ratio of girls to total campers is 8/15
Because we have 195 campers, we have 8/15 = x/195
solve for x
x= 104 girls
and we have 195 - 104 = 90 boys
Answer:
a. 360.323 m
b. 
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B =
+ 
= 
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
=
+
- 2ac Cos B
Sot hat;
=
+
- 2(187 x 308) Cos 
But, Cos
= 0
So that,
=
+ 
= 34969 + 94864
= 129833
b = 
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
=
=
=
Sin A = 
= 0.5190
⇒ A =
0.5190
= 
The bearing of the plane from its original location =
+ 
=
