Ответ:
z = 12.53 inches.
Step-by-step explanation:
Given : A right triangle. One angle measures 37 degrees. The side adjacent to the 37-degree angle measures 10 inches. The hypotenuse is labeled as z.
TO find : What is the value of z in the triangle? Enter your answer in the box. Round your final answer to the nearest hundredth.
Solution : We have given that a right triangle with one angle 37 degree and
side adjacent of 37 degree = 10 inches
Hypotenuse = z
By the cosine ration :
Cos (Ф) =![\frac{adjecent\ side}{hypotneuse}](/tpl/images/0104/4837/abb9d.png)
plugging the values of adjacent side and hypotenuse
Cos (37) =![\frac{10}{z}](/tpl/images/0104/4837/d4b13.png)
On multiplying both side by z
z (0.798) = 10
On dividing by 0.798 both sides
z =![\frac{10}{0.798}](/tpl/images/0104/4837/86567.png)
z = 12.53 inches.
Therefore, z = 12.53 inches.

Applying the trigonometry ratio, CAH, the value of z is: 12.5 inches.
Trigonometry RatiosTrigonometry ratio for solving a right triangle is given as SOH CAH TOA.
Thus:
Reference angle (∅) = 37°Adjacent = 10 inchesHypotenuse = z inchesApply CAH:
Cos ∅ = adj/hyp
Substitutecos 37 = 10/z
z = 10/(cos 37)
z = 12.5 inches.

Explanation:
The temperature of lava is so high that the moment it comes in contact with ice, it converts the latter directly into vapor, without turning it into water first. This steam essentially tries to escape through the lava.
