Answer:
The triangle C
Step-by-step explanation:
As we know:
The Law of Sines (or Sine Rule) is very useful for solving triangles:
where:
- a, b and c are sides.
- A, B and C are angles
Let analyse 3 answers:
a. Wrong, because we do not know the measure of each angle
b. Wrong, we do not the the lenght of side that is opposite the the angle 40°
c. True, we know the measure of the other missing angle is:
= 180° - 70°- 30°
= 80°
and we know one side is: 10m
Hence, using the Sine Law, we can find out the side of the other 2 sides of the triangles.
Answer: The area of the enlargement is 315cm.
Step-by-step explanation:
If the picture has 35cm as the area and it has a length of 7cm then we can find the width by dividing the area by the length.
w= 35/7
w = 5
So in this care the width of the picture in 5cm.
Now is saying that the picture's length has been enlarge or been dilated to 21 cm. To get from 7cm to 21cm you will have to multiply by 3.
In this situation, we will have to multiply the original picture's width by 3 to find it enlargement.
w= 5*3 = 15
The width is 15cm and the length is 21cm so multiply them to find the area.
A = 15 * 21
A = 315cm
Answer:
67.307
Step-by-step explanation:
30×25=750
100×80=8000
750+8000=8750
8750/130=67.307... total hits divided by total games
Answer:
201° and 60°
Step-by-step explanation:
(2)
∠ FHG = ( arc ES + arc FG ), that is
128° = ( 55 + FG ) ← multiply both sides by 2
256° = 55° + FG ( subtract 55° from both sides )
201° = major arc FG
(3)
The measure of the secant- tangent angle FTS is half the difference of the intercepted arcs, that is
∠ T = ( arc FS - arc US )
= (170 - 50)°
= × 120°
= 60°
