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.
Hello!
To find the area of the trapezoid, you use the formula A=1/2h(a+b), where a and b represent the two base lengths.
Since we already know the two bases and the height, we can just plug them into the equation to find the area.
A=1/2·15.4(26.7+9.9)
A=1/2·15.4(36.6)
A=1/2·563.64
A=281.82
The area is 281.82 ft².
I hope this helps!
Answer:
a, (x^2)^3 = x^6 = x^2.x^4
b, x^5·x^7 = x^12 = (x^3)^4
c, x^4·x^22 = x^26 = (x^2)^13
d, (x^2)^8 = x^16 = x^2.x^14
e, x^10/x^3 = x^7 = x^20.x^(-13)
f, x^(-3) = x^4.x^(-7)
g, 1/x^(-3) = x^3 = x^4.x^(-1)
Hope this helps!
