Answer:
29.56
Step-by-step explanation:
From the given diagram
x = hypotenuse
27 = adjacent
Using SOH CAH TOA identity
cos theta = adj/hyp.
Cos 24 = 27/x
x = 27/cos24
x = 29.56
Hence the value of x to the hundredth place is 29.56
Answer:
1/4 of an hour is 15 minutes
Step-by-step explanation:
Answer: x = 150/6 = 25
Step-by-step explanation:
Here is the information shown in the diagram: in triangle ABC, Angle A = 68, Angle C = 38, AB = 6, and BC = 10. In triangle DEF, Angle D = 38, Angle E = 74, EF = 15, and DE = x.)
The value of x is (Choose...4, 11, 12, 19, 20, 25).
To solve this, we notice that the sum of the angle measures mentioned is 68 + 38 + 74 = 180. Thus Triangles ABC and FED are similar by AA Similarity. It remains only to set up the proportion:
DE/CB = EF/BA
x/10 = 15/6
x = 150/6 = 25
