Answer:
16.2
Step-by-step explanation:
A trick to remember for right triangles is SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we have the side adjacent to the angle and the hypotenuse. So we should use cosine.
cos 22° = 15 / x
x = 15 / cos 22°
x ≈ 16.2
The difference of a number and seven is x - 7. So twice that, would be:
2(x - 7)
Answer:
The length of P is 34.14
Step-by-step explanation:
Using the sine law
a/sin A = b/sin B
From the question; In ΔFTP, sin T=29, sin P=110, and t=9. Find the length of P.
a = the length of P
Sin A =Sin P = 110
b = t = 9
Sin B = sin T = 29
p/sin P= t/sin T
p/110 = 9/29
Cross multiply
29 x P = 9 ×110
29P = 990
P = 990/29 = 34.13793103= 34.14
Answer:
v < 2
Step-by-step explanation:
1+4v<9
Subtract 1 from each side
1-1+4v<9-1
4v < 8
Divide each side by 4
4v/4 <8/4
v < 2
