Answer:
see explanation
Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm
Answer:
The answer is D.
Step-by-step explanation:
40.5 multiplied by 21 is 850.5
Answer:
1100000
Step-by-step explanation:
We know, I = P * R * T /100
Here, P = 10,000
R = 6%
T = 5
Substitute their values into the expression,
I = 10000 * 6 * 5 /100
I = 300000 / 100
I = 300
Final Amount = Initial Amount + Interest Amount
Final Amount = 10,000 + 300 = 10,300
So, your final answer is $10,300
Hope this helps!
